The 51000 Series Single Direction Thrust Ball Bearing has a Ball and Cage Assembly sandwiched between the ground ball track of the Housing Washer and the ground ball track of the Shaft Washer, contacting both rings at a 90-degree angle. These bearings are generally used in low speed applications and must be lubricated at installation with the appropriate grease or oil.
