Quality is not a department.
It is how we manufacture.
Since 1970, JMC has built its reputation on precision manufacturing, in-built quality circles, and a culture of continuous improvement that has produced a 0 PPM record over five consecutive years for one of India's most demanding gearbox OEMs.
Four principles that shape every bearing we make.
Precision in Manufacture
Rollers machined from special case-hardening steel, centreless ground for high accuracy and smooth finish. Hard case, tough core — engineered to withstand wear and avoid breakage.
In-Built Quality Circle
Continuous strive to break new ground in non-standard heavy-duty bearings. JMC designs and builds its own bearing-checking equipment.
Long Trouble-Free Running
Liberal roller length, controlled disposition in the cage, and ample lubrication channels deliver smooth, silent, continuous service in the harshest environments.
Continuous Improvement
Every decade has added new product lines — flexible rollers (1990s), back-up bearings for Sendzimir mills (1995), multi-row CRBs (1999), split roller bearings, universal joint cross bearings, wind gear components.
Built to specification, verified at every stage.
Centreless Grinding
All rolling elements ground to high accuracy with smooth finish for long trouble-free running.
Case Hardening
Heat treatment delivering a hard wear surface over a tough impact-resistant core.
Custom Test Rigs
JMC-designed equipment for bearing inspection, ensuring every assembly meets specification before dispatch.
Tailor-Made Design
Non-standard heavy-duty bearings designed for specific shaft, housing, load and environment requirements.
