Mahadev Enterprise

• This lineup of bearing includes a basic series that meets ISO standards, and a specified series targeting machine tools.
• A series of sealed angular contact ball bearings with prepacked grease is available.
• The Robust series of high performance bearings include, a wide lineup of bearings, ranging from highly rigid types to ultrahigh-speed types.

RHP Bearings have a long heritage, which is respected, throughout the world. RHP Bearings (Ransom, Hoffman and Pollard) was formed in 1969 as a result of the amalgamation of three of the UK's leading bearing manufacturers. RHP Bearings has gone onto field of various bearing types in a multitude of applications. NSK a major world force in rolling bearing technology is an organization committed to global localization. Recognizing the synergy with RHP since 1990, NSK joined force to create NSK-RHP which is strongly identified as a core brand by customers throughout the world.

• RHP Inch series bearing.
• RHP Bearing units incorporated into different housings.
• RHP Super Precision Bearings for Machine Tool Application.

In the field of modern machine tool building, instrument making and other engineering activities, ever-increasing demands are placed on bearing performances in the terms of higher rotational accuracies and speeds. These demands are reliably met with RHP Super Precision Bearings, which demonstrates the following distinct features :

• extreme accuracy
• high rotational speed
• minimum friction and heat generation
• controlled rigidity

NSK-RHP manufacturers three basic types of Super Precision Bearings :

• Single Row angular contact ball bearings
• Ball Screw Support Bearings
• Single row radial ball bearings

Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

• High-speed capability
• Accommodate relatively high radial loads, high axial loads in both directions and tilting moments
• Suitable where a stiff bearing arrangement is required
• Require less axial space than equivalent pair of single row angular contact ball bearings

• High-speed capability
• Accommodate relatively high radial loads, high axial loads in both directions and tilting moments
• Suitable where a stiff bearing arrangement is required
• Require less axial space than equivalent pair of single row angular contact ball bearings

Single row angular contact ball bearing These single row angular contact ball bearings can accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They can operate at high speeds and, depending on the variant, even very high speeds. They are more suitable than deep groove ball bearings for supporting large axial forces acting in one direction. • High-speed capability • Accommodate relatively high radial loads and large unilateral axial loads

NSK-RHP Super Precision Bearings:

NSK-RHP manufacturers three basic types of Super Precision Bearings:

• Single row angular contact ball bearings
• Ball screw support bearings
• Single row radial ball bearings
• Angular contact ball bearings

This is the most adaptable and important bearing within the NSK-RHP range for use in machine tool spindles. The many combinations of contact angle and preload allow precise bearing selection to cope with most arduous of requirements, be they speed or capacity. The range has preferred contact angles 15 degrees and 25 degrees and laminated phenolic resin cages. Bearings can be supplied singly, in paired units or multiple sets.

The NSK-RHP Excel range has been introduced in response to industries need for higher speeds and has a larger number of balls. They also offer higher stiffness. They are dimensionally interchangeable with bearings with normal ball diameter. The NSK-RHP Ultra range is designed for particularly high speed application.

The NSK-RHP Excel, Ultra and normal ranges can be supplied with silicon nitride (ceramic) balls. These offer higher speeds and lower operation temperatures, as well as enhanced stiffness.

Ball Screw Support Bearings:

• NSK-RHP has available a comprehensive range of ball screw support bearings, cartridge and pillow block
• Units Ball Screw support bearings with their high rigidity, low torque, simple mounting and elimination
• Of the need for preload adjustment provide ideal support solution
• RHP ball screw support bearings are

The design of SKF double row angular contact ball bearings corresponds to two single row angular contact ball bearings arranged back-to-back.

Bearing Features:

Less axial space: Can be used for applications where two single row angular contact ball bearings arranged back-to-back take up too much axial space.

Accommodates radial as well as axial loads in either direction

Accommodates tilting moments
