Double row cylindrical roller bearings have a high load carrying capacity because of the high number of cylindrical rollers in each row, and the exclusive optimized roller crown profile which results in the best load distribution. The cage is of solid machined brass construction, making this bearing suitable for rugged applications.

The bearing bore is tapered (taper =1: 12). The desired radial preload or radial clearance can be set by an axial adjustment on the conical shaft. Generally, the bearings should be mounted with zero clearance to a very slight preload.

Cylindrical rollers generally have lower limiting speed than ball bearings. They are the limiting factor when used in conjunction with spindle bearings on the work end of a spindle.

Cylindrical roller bearings can be lubricated with either grease or oil.

Applications of BEART high precision single row cylindrical roller bearing: machine tool, spindle, measuring equipment.
