Why Choose BMT Bearings

High Load Capacity: Single Row Cylindrical Roller Bearings reaches up to 120 kN in dynamic radial load.We support medium-duty equipment with ease.

Low Friction Design: All BMT bearings have done good superfinish on roller surfaces which can help machine to reduce heat generation and extend service life by 40% comparing to standard models.

Versatile Applications: BMT bearings are suitable for apply high RPM(above 6, 000 rpm).Especially, apply for conveyors, motors, and machine tool spindles etc.

Precision Engineering: BMT bearings raceway roundness controlled within 0.002 mm, this precise telorance ensures minimal vibration and noise.

Customer Concerns

Longevity in Continuous Operation: One of our food processing client reported extending bearing replacement period from 8 to 14 months after switching to BMT bearings. Due to our bearings long lifetime service, this advantage reduced machine downtime around 35% and saved over 200, 000 RMB annually in maintenance costs.

Cost-Effectiveness: Our Single Row Cylindrical Roller Bearings' competitive price combined with ABEC-1/ABEC-3 precision which offers 20% better value than similar products in the market.

Customization Options: We adjust internal clearance based on working conditions which ensure flexable fit for unique equipment requirements.

Product Advantages

In conveyor systems, our bearings demonstrate exceptional resistance to shock loads. One of our client was a logistics company which used our N310 model reported a 25% increase in system uptime.Attributed to the bearing’s ability to handle sudden starts and stops. Similarly, in woodworking machinery, the low-friction design has helped reduce energy consumption by 12% and lead to significant cost savings.These advantages stem from our use of good quality bearing material and strict testing process.Each bearing undergoes 100% vibration and load capacity checks before delivery.

Usage Instructions for Performance

Installation Tips: Our Single Row Cylindrical Roller Bearings apply a thin layer of grease to the raceways before mounting.This technology ensure the shaft and housing are clean to prevent debris damage.

Lubrication Schedule: For continuous operating machine, re-lubricate is very important during every 2, 000 hours. In environments exceeding 150℃, we suggest to use high-temperature grease.

Maintenance Checks: Regularly inspect for unusual noise or heat, it may indicate misalignment or wear.Then we shoule do necessary action before machine shutdown.
