A RAS Tapered roller bearings are bearings that can take large axial forces (i.e., they are good thrust bearings) as well as being able to sustain large radial forces.

A RAS ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads.

A RAS spherical bearing is a bearing that permits angular rotation about a central point in two orthogonal directions (usually within a specified angular limit based on the bearing geometry).

RAS follows stringent Quality checks & control measures to ensure highest quality products and to achieve international quality standards. Quality Management is applied from front design to dispatch of products to meet our aim of zero defect supplies. All our products undergoes most intensive testing on state of the art metallurgical & instruments.
For testing tensile and compression strength on bearing components (Max. Capacity of 10 Metric Tons) with graph facility for records.
Shadow & surface profiles X10, X20, X50 are available to measure radius, angle and distance in X & Y axis on components under test. Print out of results optional.
Hardness on case hardened surface measured in vicker’s scale at Min. load of 10 gm to Max. 1 KG. Display of results are digital.
Waviness on ball tracks are measured on this m/c. Frequency of waviness is displayed in low, medium & high frequency scales digitally.
Bearing torque testing is computer aided. The data is analysed by our R & D team during new development of the bearings & recorded.
Noise on bearings are 100% tested on noise testing m/c with inner race rotating and outer race steady. Display of noise in µm/sec at three frequencies low, medium & high and compared with standard.
Phosphate treatment of metals of Phosphating, as one of the most useful and effective method for the protection of iron and steel surfaces from atmospheric corrosion. Apart from its anti-rust character, the coating provides an ideal base for an organic finish and as an aid to lubrication. It also prevents wear in sliding or frictional parts. The coating provides myriads of oil reservoirs effective in reducing friction. Such uses of Phosphate coating are commercially very important.
Hard chromium (chrome) is a functional relatively thick coating deposited on a metallic substrate in order to impart particular surface properties.
- High Hardness (About 1000 HV)
- Low coefficient of friction
- Wear resistance
- Corrosion resistance
- Galling resistance
Incoming raw materials are analysed for its chemical composition by spectro chemical analysis and metallurgical tests for microstructure analysed by metallurgical microscope & compared with standards and image analyser. Only OK materials are cleared for further processing.
