Frequently Asked Questions
Q: What are the dimensions of SKU 5776 bearing cup?
A: SKU 5776 has an inner diameter of 57.76 mm, outer diameter of 74.42 mm, and width of 16 mm. This bearing cup is manufactured from high carbon chrome steel (GCr15 or equivalent grade) with machined steel cup construction.
Q: What type of bearing is SKU 5776 and what does it do?
A: SKU 5776 is a one-way sprag clutch bearing used in precision industrial drive and wheel torque transmission applications. The sprag design allows free rotation in one direction while locking in the opposite direction, commonly used in primary drive assemblies of electric lift trucks.
Q: Is SKU 5776 sealed or unsealed?
A: SKU 5776 is supplied as an open bearing without seals. This unsealed design is standard for precision industrial drive applications where the bearing operates in a controlled environment within the equipment assembly.
Q: What equipment does SKU 5776 fit?
A: SKU 5776 is designed for electric lift trucks and similar material handling equipment requiring replacement bearing cups in primary drive assemblies. Confirm dimensions match your specific equipment before ordering, as sprag clutch bearings must fit precisely in torque transmission systems.
Q: What is the material composition of SKU 5776?
A: SKU 5776 is manufactured from high carbon chrome steel (GCr15 or equivalent grade). This material provides enhanced durability, load capacity, and wear resistance required for industrial drive applications under continuous torque and load cycling.
Q: How do I know if SKU 5776 needs replacement?
A: Signs of bearing failure include grinding noise from the primary drive assembly, loss of one-way locking function, excessive play or wobble, or visible metal scoring on the bearing surface. If the truck loses drive torque transmission or exhibits slipping during load operation, the sprag clutch bearing may need replacement.
