Company History & Brief Overview

Protec was established in the year 2011 in the industrial city of Rajkot, Gujarat-India, with the core objective to produce Tapered Rollers efficiently using the best in class manufacturing practices. Ever since inception, we have strived to adopt internationally competitive processes which resulted in highest quality components.

In the year 2018, PROTEC acquired a Tapered Roller Manufacturing facility from South Korea called Korea Ball & Roller (KBR). KBR was previously a part of FAG, Korea.

KBR was a supplier to major Taper Roller Bearing Co’s like NSK, Schaeffler, SKF, Iljin, etc. Through this acquisition, PROTEC is now an approved supplier to major Taper Roller Bearing manufacturers around the world.

For this, we have also built a new state-of-the-art modern production facility on our newly acquired 10 acre (40,468 square meters) land at Chappra Village, Rajkot.

On achieving full capacity, this phase of the new plant to be India's largest production unit from a single location for end-to-end manufacturing of Ready-For-Assembly Taper Rollers meeting international quality standards.

Salient Features of the New Plant are:

  • IATF:16949, ISO 9001 Certified, TPM JH Step & Lean Manufacturing Compliant Plant.

  • Technology Transfer through acquisition to follow International best practices.

  • New Plant implements Industry 4.0 through Factory Process Automation.

  • First time in Indian Roller Industry of New Cold Forging Technology from National, USA.

  • Best-in-class grinding, lapping, sorting & visual inspection equipment installed.

  • Certified Operators with I-L-U-O levels of Skills Upgradation.

  • Dedicated Research, Innovation & Execution Teamfor new developments.

The end use applications of our taper rollers are critical towards daily operations in automotive, trucks, machine tools, robots, automation equipment & more.

New Product Innovations

The necessary elements for the life of a bearing, its noise and its load carrying capacity are:

Quality of Steel Product geometryCondition of contact surface Heat treatment process

We procure steel only from customer approved sources and have the incoming material monitoring mechanism in place. We place critical focus on endface radius & raceway profile. Thus, establishing a perfect contact between the bearing flange & the roller endface. Various raceway profiles (convex, log or straight) reduce bearing stress and increase its wear resistance. Our automated processes commit to optimum roller geometry.

Taper Rollers for Next Gen Bearings

The global shift from Internal Combustion Engine vehicles to Electric Vehicles (EV’s) is more rapid than expected. Bearing manufacturers are responding to this challenge with new and improved product categories catering to the specific requirements of these upcoming technologies.

For EV’s, the usage of the bearings will reduce but there will be a new class of improved technologies & functionalities required in those bearings. Reduced Friction, lightweight, increase in life, etc will be few of the critical areas as mileage efficiency expected out of EV’s will be at least 3 times of the normal IC engines. Higher efficiency transmission systems will be important to achieving fuel efficiency.

Class XE

PROTEC has developed a new Class of Taper Rollers, Class XE (Extreme Efficiency), suggested for use in electric vehicle (EV) transmission systems. The Class XE taper roller, is a considerable improvement in all the main quality parameters in addition to honed end faces. Thus, reducing friction at the time of contact with flange, lowering noise and improving performance.
