Boston International Cairo Circles Antique Copper Guest Caddy

 Ean: 0704266032187   |    PartNumber: CAD18239   |   Asin: B079R4WPSY

Metal framed napkin caddy keeps disposable paper napkins, or folded linen ones, handy and clean. Flat caddy makes single napkins easy to pick up and accessible from all angles, unlike upright holders that napkins fold down over each other in and have to be accessed from only one direction. Use to keep the dinner table or buffet organized, place by the kitchen or bathroom sink as a hand washing valet, or keep on the bar for mixed drinks, cocktails and appetizers. It was the love and appreciation of fine design along with the opportunity to create and market well-made yet affordable products that lead Jonathan Newman and Steven Faulkner to found Boston International (BI) in 1986. In the beginning, BI was a boutique line with beautiful hand-made paper products from smaller suppliers in Italy, Spain, Germany and the UK. Through the years, the company developed and grew. In 1996, Boston International added Ideal Home Range (IHR) to their product mix and very shortly after that, BI began its relationship with New York's Metropolitan Museum of Art. Through the combination of these lines, BI has become a major force in the gift industry today. Ideal Home Range has gained a richly deserved worldwide reputation as the preeminent manufacturer of paper napkins in all sizes, from 5 x 5-inch cocktail napkins, to 6.5-inch square lunch napkins, to 8.5 x 4.5-inch guest towels that can double as buffet napkins. Browse all the thick, 3-ply napkins from IHR for casual and elegant designs to fill any and all napkin caddies from Boston International.

Features

  • Decorative rectangle napkin holder organizes your kitchen table, buffet, bar, or bathroom
  • 8.75 x 4.75-inch x 2.75-inch tall tray neatly stores an ample supply of standard rectangle guest towels/banquet napkins

Boston Gear YB12 Spur Gear, Steel, Inch, 16 Pitch, 0.375" Bore, 0.875" OD, 0.750" Face Width, 12 Teeth

Model: YB12   |    Mpn: YB12   |    Ean: 0781711099162   |    PartNumber: YB12   |   Asin: B004NYAJ0K

The Boston Gear low carbon steel spur gear with 20-degree pressure angle (PA) and a diametral pitch (DP) of 16 transmits torque between parallel shafts to provide rotational power to another part of a motorized system. It has a 20-degree pressure angle for lower contact ratio between gears, resulting in higher load capacity than smaller pressure angles, and a 16-diametral pitch for applications requiring a balance between transferring torque and controlling changes in speed and direction of rotation with precision. This spur gear, which can mesh only with spur gears that have the same pressure angle and diametral pitch, is made of low carbon steel (.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion. This Boston Gear spur gear is suitable for use in a variety of commercial and industrial applications, such as construction equipment, aeronautics, conveyors, and manufacturing equipment, among others.

Spur gears, the most common gear type, have a circular or cylindrical shape with teeth bordering the outer perimeter and are used for transmitting rotational torque and motion between parallel rotating shafts. A spur gear's pressure angle (PA), diametral pitch (also called DP or pitch), and its material are important factors to consider when purchasing. Gears come in several types for use in different power transmission configurations and for different applications, including bevel and miter gears (for rotating shafts perpendicular to each other), change gears (to increase or decrease torque and speed), helical gears (for high rates of rotational speed), internal gears (where one gear is nested inside the other), rack and pinion gears (for turning rotational motion into linear motion), and worm gears (for perpendicular shafts in tight spaces and quiet operation). Gears are suitable for use in the agriculture, automotive, construction, mining, and packaging industries, and can be found in a variety of machines, including bicycles, automobiles, and elevators, among others.

Boston Gear manufactures a variety of gear drives, variable speed drives, clutches, and the components that comprise these systems including sprockets and bearings. Their manufacturing designs, production, and inspection meet International Organization for Standardization (ISO) standards for quality assurance. The company, founded in 1877, is headquartered in Charlotte, NC.

Features

  • Transmits torque between parallel shafts to provide rotational power to another part of a motorized system
  • Pressure angle of 20 degrees for a lower contact ratio between gears, resulting in higher load capacity than smaller pressure angles
  • Diametral pitch of 16 for applications requiring a balance between transferring torque and controlling changes in speed and direction of rotation with precision
  • Low carbon steel (.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion

Boston Gear H3220 Spur Gear, 14.5 Pressure Angle, Steel, Inch, 32 Pitch, 0.250" Bore, 0.687" OD, 0.188" Face Width, 20 Teeth

 Ean: 0781711095409   |    PartNumber: H3220   |   Asin: B002E7FTHQ

The Boston Gear low carbon steel spur gear with 14.5-degree pressure angle (PA) and a diametral pitch (DP) of 32 transmits torque between parallel shafts to provide rotational power to another part of a motorized system. It has a 14.5-degree pressure angle for a higher contact ratio between gears than larger pressure angles, resulting in quieter operation, and a 32-diametral pitch for applications for applications where controlling changes in speed and direction of rotation with precision is more important than transferring torque. This spur gear, which can mesh only with spur gears that have the same pressure angle and diametral pitch, is made of low carbon steel (.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion. This Boston Gear spur gear is suitable for use in a variety of commercial and industrial applications, such as construction equipment, aeronautics, conveyors, and manufacturing equipment, among others.

Spur gears, the most common gear type, have a circular or cylindrical shape with teeth bordering the outer perimeter and are used for transmitting rotational torque and motion between parallel rotating shafts. A spur gear's pressure angle (PA), diametral pitch (also called DP or pitch), and its material are important factors to consider when purchasing. Gears come in several types for use in different power transmission configurations and for different applications, including bevel and miter gears (for rotating shafts perpendicular to each other), change gears (to increase or decrease torque and speed), helical gears (for high rates of rotational speed), internal gears (where one gear is nested inside the other), rack and pinion gears (for turning rotational motion into linear motion), and worm gears (for perpendicular shafts in tight spaces and quiet operation). Gears are suitable for use in the agriculture, automotive, construction, mining, and packaging industries, and can be found in a variety of machines, including bicycles, automobiles, and elevators, among others.

Boston Gear manufactures a variety of gear drives, variable speed drives, clutches, and the components that comprise these systems including sprockets and bearings. Their manufacturing designs, production, and inspection meet International Organization for Standardization (ISO) standards for quality assurance. The company, founded in 1877, is headquartered in Charlotte, NC.

Features

  • Transmits torque between parallel shafts to provide rotational power to another part of a motorized system
  • Pressure angle of 14.5 degrees for a higher contact ratio between gears, resulting in quieter operation than larger pressure angles
  • Diametral pitch of 32 for applications where controlling changes in speed and direction of rotation with precision is more important than transferring torque
  • Low carbon steel (.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion
