Mounted ball bearing unit
7/8" - 4 15/16"
SealMaster
* 7/8" - 4 15/16"
* Standard and medium duty series
# Double set screw locking incorporates extended inner races on both sides of the ball path resulting in a total of 4 set screws (2 on each side) for better load distribution, resulting in greater holding power when operating at high speeds and when vibration may be present.
# Wide outer ring design provides increased grease capacity to lubricate the bearings.
# Anti-rotation - pin & dimple system prevents the bearing OD from creep/rotation due to vibration over time while providing a full ± 2° of static misalignment.
# Direct lube - pin & dimple system provides a direct lubrication path into the bearing, eliminating the need to channel grease around a lubrication groove common on standard mounted ball bearing units.
# Felt labyrinth seal with rotating flinger directs contamination away from the sealing surfaces. Alternate seal options available upon request, see Sealmaster Custom SelectTM for more information.
# Black oxide standard on inner/outer rings and seal components inhibits corrosion.
# Zone hardened inner race provides a fully hardened ball path while leaving the race extensions unhardened, allowing better set screw holding power.
# Length through bore is longer than most competitors for greater shaft stability.
# Land-riding brass retainer has high strength, minimizes friction and provides maximum grease circulation.
# 120° balanced set screw position provides three-point balanced contact that minimizes vibration, reduces noise and improves reliability of the shaft assembly.
