McGill 4-1/4"-ID NEEDLE ROLLER BEARINGS MCG MR-68
McGill® CAGEROL® machined race needle bearings are manufactured from bearing quality steel. Most sizes use crowned or end relieved, rollers to help reduce end stresses and allows for greater misalignment. The rollers are separated by a steel retainer (cage) to help achieve higher speeds and provide a lubricant reservoir. CAGEROL® bearings are constructed with radial lubrication hole and groove on the outer and optional inner raceway (MI series) for relubrication through the housing or shaft. Other options include a variety of seal configurations to either help prevent contaminant entry or contain the lubricant.

Mayhew™ 21501 PRO™ Extra Long Pin Punch, 3/16 in Hex Punch, 7-7/8 in OAL, Alloy Steel
O-rings are closed circular rings of circular cross-section. They are made through vulcanization from form tools as a complete ring. The sealing function of the O-ring is achieved by the deformation of the cross-section when installed and compressed in its housing. The O-ring can be compressed either radially or axially in its installation housing. In operating conditions the pressure exerted by the media reinforces the sealing function, as under pressure the elastomer material functions as a non-compressible fluid.

Browning® 767381 VE 200 Standard-Duty Straight Bore Ball Bearing Insert, 1-7/16 in Dia Bore, 2.8346 in OD, 2-1/64 in W, 5782 lb Dynamic/3493 lb Static Load
Browning® mounted ball bearings feature multiple housing styles, materials and configurations, an extended inner race insert bearing with ball riding nylon retainer. The insert features a rivet to prevent outer ring rotation and is available with setscrew, eccentric or BOA concentric locking collar. The contact seal with black oxide treated flinger provides a good balance between contaminant resistance, grease loss and friction.
Gates® Power Transmission Super HC® Molded Notch PowerBand® 10/5VX1320 Heavy Duty Molded Notch V-Belt, 5VX Section, 5/8 in W Top, 132 in L Outside, 35/64 in THK, EPDM
When your power transmission application needs a high horsepower solution but is constrained by drive weight or physical space, the answer is Super HC™ Molded Notch belts. Our proprietary ethylene construction process provides a superior combination of flex and load-carrying capacity, transmitting up to three times the horsepower versus comparably sized belts. Super HC MN V-belts put more power where high speeds, high speed ratios or small pulley diameters are required, offering significant benefits over classical section V-belts.
