The INA KRE-PP cam follower is a rolling element built to carry radial loads where the running surface is a cam or the shaft itself. It fits cam drives, linear guides and lifting mechanisms, where it keeps motion smooth and precise. The PP version adds seals on both sides, which keeps contaminants out in tough plant environments.
Reading the code is straightforward. KRE marks the series: a needle roller cage with a cylindrical outside profile. The number after it gives the outside diameter in millimeters, so KRE16-PP measures 16 mm across and KRE19-PP measures 19 mm, with the rest of the range following the same logic. The PP suffix tells you the cam follower has protective seals on both sides. That makes it easy to match a size to the space you have.
These cam followers turn up in machine tools, packaging lines, conveyors, automation cams, presses and automotive work. Food and beverage plants also use them, since they tolerate washdown and cleaning routines. Because they handle radial and axial loads, they suit both oscillating and rotating motion.
Selection comes down to three things: the radial load the position will see, the speed it runs at, and the surrounding conditions. Choose the PP sealing when dust, chips or liquids are present. At mounting, line the cam follower up accurately with its raceway and check that the shaft has the right hardness and surface finish. Use the specified lubricant, and when relubrication is due, go through the channel provided for it.
KRE-PP cam followers can be swapped for equivalents from other makers that use the same dimensional naming. Tolerances and seal type are not always the same, so it pays to confirm them. Send our technical team the full part number and your operating conditions and we will check compatibility. MR supplies the INA brand and can advise on the selection.

Frequently asked questions
- What does the PP suffix mean on KRE cam followers?
- It means the cam follower carries protective seals on both sides. Those seals keep contaminants out and hold lubricant in, which helps the bearing last longer where dust, chips or moisture are present.
- How do I choose the right KRE cam follower size?
- The number in the designation is the outside diameter in millimeters. Pick the size that fits your available space and the load you need to carry. If you are unsure, send us your application measurements on WhatsApp.
- Are KRE-PP cam followers interchangeable with other brands?
- They can be exchanged with cam followers from other manufacturers that share the same dimensions and specifications. Tolerances and sealing can differ, so it is worth confirming before you commit.
