Sackorange 608 ZZ Skateboard Bearings, Double Shielded,8x22x7 Miniature Ball Bearings Pack of 20)

 Ean: 0730060656304   |    PartNumber: CS-sack-038   |   Asin: B07216D1SZ

This 608ZZ shielded 8x22x7 miniature ball bearing is a single-row bearing for supporting radial loads. The bearing is made of carbon steel for durability and resistance to deformity under heavy loads, and is shielded to keep lubricant in and contaminants out.
it has a revolutions per minute (RPM) limit of 34,000 with grease lubrication. The dimensions of this bearing make it suitable for use in skateboards, inline skates, and scooters, among others. These bearings come in a pack of 20.
Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or
tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The
shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics,
dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

Package included:20 x 608zz

Features

  • Single-row bearing for supporting radial loads
  • Shields on both sides of the bearing to keep lubricant in and contaminants out
  • Carbon steel for durability and resistance to deformity under heavy loads
  • 34,000 rpm limit with grease lubrication
  • Dimensions suitable for use in such applications as skateboards, inline skates, and scooters

Linear Motion 12 mm Shaft, 13" Length, Chrome Plated, Case Hardened, Metric

Model: kit1002   |    Mpn: kit1002   |    Ean: 0692128470409   |    PartNumber: kit1002   |   Asin: B002BBJ0CA

This linear motion shaft is 12 mm in diameter and 13" long, chrome plated, and case hardened, and is suitable for use with linear support blocks and closed type slide units in linear motion applications. The high-carbon steel shaft is chrome plated for corrosion resistance, case hardened for wear resistance, and precision ground for consistent ball bushing radial clearance. The shaft diameter and length are specified for accurate fit and this shaft is suitable for use in applications, such as measuring systems, printing equipment, and computer numerical control (CNC) tools.

Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.

Features

  • Round steel shaft for use with linear support blocks and closed type slide units in linear motion applications
  • Chrome plated for corrosion resistance
  • Case hardened for wear resistance
  • Precision ground for consistent ball bushing radial clearance
  • Shaft diameter and length specified for accurate fit
