Stud Type Ball Bearing Track Roller With Crowned Running Surface

Stud Type Ball Bearing Track Roller ZL2,ZL52,KR52,ZLE52

Heavy-section roller stud, with or without eccentric collar

Stud type track rollers have outer rings with a crowned outside surface, heavy-section roller studs and ball and cage assemblies with plastic cages.The yoke type track rollers are available with and without an eccentric collar.

For ease of mounting, the roller stud is produced in one of the following designs:
● with a threaded hole and mounting slot
● with an external thread and hexagonal socket
● with an external thread and flat areas on both sides

Stud Type track rollers without eccentric collar

Stud type track rollers without an eccentric collar are suitable for applications where a defined requirement for adjustment in relation to the mating track on the adjacent construction is not required

Stud Type track rollers with eccentric collar

Stud type track rollers ZLE52 have an eccentric collar. The eccentric collar can be used to set the outside surface of the outer ring clearance-free against the mating track. This gives optimum geometrical locking between the track roller and mating track. Furthermore, larger manufacturing tolerances can be tolerated in the adjacent construction. The load distribution when several stud type track rollers are used is also more uniform. For countertensioning during fitting, this series has flat areas on both sides of the roller stud. Threaded connections must be provided on the two end faces for relubrication, dimensions.

Premium Quality Assurance

All of C&H track roller bearings are made from ultra-clean bearing steel and premium quality components, with precision accuracy and smaller runout, filled with high performance lithium soap grease. The long life serive can help user to save more money.
