Product Profile

Cylindrical rollers are used in bearings where the majority load is in the radial direction. Although mostly cylindrical in shape, some specialist bearings have convex barrel shapes or concave profiles depending on the application type and conditions. Pure cylindrical roller bearings cannot support ...

  • In addition to above mentioned specifications rolling elements with special tolerance limits (plus tolerances, hardness as low as 45 HRc etc) can be supplied on request.
  • In addition rollers can be provided with end drops (Type ZB) as a stress relieving feature thereby increasing life performance.
  • In addition rolling elements can be manufactured with different materials (Stainless Steel SS, Mild Steel MS) if the quantities required are sufficient for economical production.

Mec Bearings Pvt. Ltd. (Manufacturer)

MEC Bearings Private Limited is a company dedicated and devoted solely for the manufacture of precision cylindrical components involving close dimensional tolerances, high surface finish, special profiles and high volumes. Because of our strong commitment to QQS (Quality: Quantity: Service), the company has earned worldwide reputation of "High Quality Engineering At Reasonable Cost".

MEC was established in 1988 as a specialised manufacturer of High Precision Rolling Elements Since the beginning, we have consistently demonstrated the ability to meet the most stringent quality standards by constantly upgrading our facilities and investing in R & D activities. Today, we are proud to be associated with major OEMs in the Indian and international market, with a strong presence in after market as well.

MEC is capable of producing precision rolling elements involving close dimensional tolerances (Needle Rollers & Cylindrical Rollers) to cylindrical pins which can be used as Shaft / Axle in variety of applications.

MEC produces wide range of rolling elements according to DIN 5402 / ISO 3096 standard, in Bearing Steel (Grade SAE 52100 or equivalent), having hardness (670+170) HV or (58+7) HRC after heat treatment.

Applications
They are primarily used as bearing rolling elements to transmit torque and reduce friction. Alternatively they can also serve as shafts or locating pins in some applications Some of the most common applications are :
  • Bearings
  • Tripod Joints
  • Linear Guide Ways
  • Roller Clutches
  • Universal Joint Crosses
  • Linear Seat Tracks
  • Planetary Gear Boxes
  • Starter Drives

Quality
EC follows internationally prescribed standards (ISO 9001:2008, ISO 3096:1996, DIN 5402:1993) to ensure that the quality of products is not compromised at any stage of production. Further these are regularly monitored by qualified personnel dedicated to this specific responsibility.

All the relevant characteristics of the product for each production batch is monitored right from the incoming raw material to finished goods packing stage.
