- Ability to carry radial and axial load in one direction, because an axial component of force is produced when this type of bearing is loaded radially, two bearings are used together facing one another or two or more bearings are matched and used
- There are the standard, medium and steep type which are different in contact angle size, medium tapered metric series bearing are identified by the supplementary code "C" which is added as a suffix to bearing numbers
- Bearing whose cup width, cup small inside diameter and contact angle are determined in accordance with ISO 355 specifications are identified by the supplementary code "J" as suffix

TRAKROL® bearings feature black oxide treated bearing steel. They utilize either a precision ball or tapered roller bearing insert for longer operating life under combination radial and thrust loads. The capacity for combination loads allows the TRAKROL® bearing to be available in plain (cylindrical), V-groove and flanged outside diameter in both stud and yoke styles. Small sizes less than 3 in outside diameter or point diameter use sealed ball bearing inserts. They also use a NYLAPLATE® seal for additional protection. Stud type configurations utilize a metal end plug seal on the roller face providing a long lasting seal. Both bearing types provide a large internal grease reservoir along with special sealing. This makes TRAKROL® bearings an excellent choice where reduced maintenance is required.
