Bearings #5141639

These high capacity thrust bearings are a perfect replacement for Timken, NTN, and other brands.
T series roller thrust bearings are used in a variety of industries including material handling, heavy equipment, and oilfield equipment.
These bearings are conveniently held together by a steel shroud which both facilitates assembly and protects the rolling elements from contamination.
Additional sizes can be provided with short lead times and low minimums.

The bores of mast guide bearings are fitted, as with any standard industrial bearing.
Unlike typical industrial bearings however, the outer diameter of a mast guide bearing
acts directly against a steel mast rail.
Depending upon the design of the mast and fork carriage assembly,
mast guide bearings can be subject to very high radial and thrust loads,
as well as high intermittent shock loads.
Mast guide bearings are intended for low speed, high load applications.
The seals are very tight fitting.
The grease fill is very high, typically over 90%.
The internal design (ball and roller complements) maximizes the load capacity.

Roller bearings, compared with equivalent sized ball bearings, can handle generally higher loads, at generally lower limiting speeds.
Also, given the same load rating, roller bearings are generally more compact than ball bearings.
The Enduro roller bearings listed here are of two types:
1. MR series, with their corresponding MI series inner rings.
2. Various track roller types MI series inner rings
Designed to work with both MR series outer races, as well as SRF series track rollers.
The advantage that MI series rings offers is that when the bearing is worn, only the inner ring, rather than the entire shaft, needs to re replaced.
Also the wide range of sizes allows for flexibility of design; the same inner ring can be combined with various outer raceroller assemblies, and vice versa.

All MI series inner rings incorporate oil holes and grooves for lubrication systems that are designed as part of the shaft.
Track Roller Types
Cam followers and Yoke roller (CF, CFE, CFH, CYR, KR, NUTR, and SRF) are all track roller types.
Outer races of these bearings run directly on a track or other wear surface.
Bearings are not designed to be pressed into a housing.

Cam follower types (CF, CFE, CFH, KR) do incorporate re-lubrication features into the integral shaft.

Cam followers and yoke rollers are used in a wide range of industries: material handing and conveying, industrial trucks, food processing, textiles and general machinery.

The preferred set up for Enduro cam followers is sealed with a internal hex recess (SB suffix)
Yoke rollers are delivered sealed as well
Unsealed versions are available, as well as other options such as special coatings, special dimensions, OD profiles etc.
