Precision Radial Bearing 61805

The Tritan 61805 2RS PRX is a metric radial ball bearing built for rotating shafts in industrial machinery and power-transmission systems. Its 25 mm bore and 37 mm outside diameter suit standard housings where a compact cross-section is required. Maintenance teams and OEM engineers specify this ABEC 1 unit for general-purpose radial loads.

Double-Sealed Alloy Steel Cartridge

Dual contact seals retain the factory Polyrex EM grease and exclude contaminants in oily or greasy environments. The alloy-steel rings and AISI 52100 grade balls deliver a dynamic radial load capacity of 1,010 lbf within the 7 mm outer-ring width. The single-piece steel cage maintains ball spacing under continuous rotation without a retaining ring.

Drop-In Replacement for 61805/6805 Housings

The bearing slides into existing 25 mm shafts and 37 mm bores with a bore tolerance of +0/-0.1 mm, requiring no machining changes. Its metric envelope frees up axial space compared with wider series bearings while the contact seals eliminate the need for external seal assemblies. Buyers needing higher precision grades or different seal materials must source alternative part numbers.

Questions about this item

Will the 25 mm bore fit the shafts I already use on my equipment?

The bearing has a 25 mm bore with a tolerance of +0/-0.1 mm, so it matches standard 25 mm shafts used in metric power-transmission setups.

How can I verify the 61805 2RS PRX is running correctly after installation?

The double contact seals and Polyrex EM grease should keep the bearing quiet and smooth under loads up to 1,010 lbf dynamic radial capacity.

Does the box include a retaining ring or must I order one separately?

The specifications state no retaining ring is included, so you will need to source a compatible circlip if your housing requires axial location.
