Shafts are elongated, rod-shaped devices that provide linear or rotary motion for power transmission applications. Shafting can be put in three main categories, standard, TGP and precision grades.

Standard shafting is normally made of cold rolled steel, is available in standard 36” lengths and is available with or without keyways. Typically the end user can cut the shaft to size for applications that do not require precise tolerances. Bearing Service stocks most common inch sizes of cold rolled steel shafting at our branch locations.

TGP shafting (turned, ground and polished) is machined cold rolled steel and holds considerably tighter tolerances than standard shafting. TGP shafting normally is cut to size per customer request. TGP shafting can be utilized to run components such as mounted bearings, gears, sheaves and sprockets, but normally would not be utilized on most linear or precision bearing applications.

Precision shafting provides the highest degree of overall accuracy, concentricity, straightness and surface perfection. Utilizing precision shafting greatly increases bearing and system life. Precision shafting is available in an assortment of diameters, including inch and metric, and can be supplied at either standardized lengths or can be cut to length.

The tolerances of precision shafting are divided into three main classes, L, N and S. Precision shafts are made of alloy steel, carbon steel, or stainless steel, and then case-hardened, through-hardened, or annealed. Please contact Bearing Service to assist in recommending the correct shafting for you application.
