Four row cylindrical bearings

A HEFTY CHALLENGE: Tailor-made 4 row cylindrical bearings

An Italian customer recently challenged the BMI team’s strong engineering knowledge to develop a special 4 Row Cylindrical Roller Bearing for heavy machinery for steel plant application.

Weighing nearly 40 kgs with an outer diameter of 290mm, this bearing was one of the most challenging projects taken up by BMI. The BMI production team successfully executed the project within a short span of 12 weeks.

To deal with the heavy radial load application, the engineering team used Special steel 100CrSiMn6 for better results. The grading of cylindrical rollers was achieved within 3 microns for better accuracy. Given the satisfactory performance of the bearings customer has expressed interest in developing other large bore bearings for their machinery. Not only was BMI able to offer performance equivalent to European brands we were also able to offer faster delivery and smaller MOQ (Minimum Order Quantity).

This customer breakthrough was very important for BMI to establish its name in the steel industry as this customer has a long standing reputation for building machines for steel plants for more than 50 years.
