Cam Follower and Track Roller

A cam follower and track roller is a cylindrical roller bearing with an integral shaft or stud, designed so that the outer ring rolls directly on a cam, a guide, or a support surface. It is selected by the ring diameter and width, the mounting type — threaded stud or hole — the outer profile shape, and the sealing. In this subcategory there are 192 SKF references, all from the SKF brand.

The series are identified by their prefixes. KR and KRV designate rollers with an integral stud and thread; the V indicates a crowned outer profile, which tolerates minor misalignment. KRE adds a hexagon head for mounting. NATR and NATV are track rollers without a stud, with a bore; the V again marks the crowned outer profile. NUKR and NUKRE combine a threaded stud with a crowned outer profile. PWKR and PWTR correspond to double-row designs. STO and RSTO are thin-walled track rollers without a stud for compact spaces. The suffixes PPXA, PPX, XA, X, 2RS, and XTN indicate sealing, shields, or cage and lubrication variants.

Typical applications include cams in machine tools, linear and rolling guides, conveying systems, automation equipment, and mechanisms where precise rolling contact with high radial load is required. In these points the roller works under continuous stress and dirt, so the sealing and the outer profile determine the service life.

An equivalent from another brand also helps. With that data the corresponding SKF reference is identified and a quote is sent by WhatsApp or email.
