The unit's machined brass cage improves performance in heavy-duty and poorly lubricated conditions. Axial and internal clearance ranges permit load sharing between the two rows of balls for cooler operation, reduce lubricant degradation, and minimize destructive skidding in the inactive row. A range of seals, shields, and snap-ring options are available.
