Quotes - Sales - EngineeringBearing Oil Cooler
Compact air-cooled oil coolers are ideal for bearing lubrication circuits, efficiently removing heat from low-flow oil returns to bearings in spindles, motors, gearboxes, pumps, fans, and rotating machinery — preventing overheating, varnish buildup, and bearing failure.
- Motor-Mounted Air Cooled: BM Series mounts directly to TEFC electric motors (NEMA 48–365 frames), providing integrated bearing oil cooling with minimal space and easy installation.
- Low-Flow / Low-Pressure: Designed for typical bearing lube returns with NPT/SAE connections and 300°F / 300 PSI ratings.
- Standalone Electric Fan: BME Series uses compact 1/40 HP 115V motors in single or two-pass configurations — perfect for remote or non-motor-mounted bearing oil cooling.
- Applications: Spindle bearings, motor bearings, gearbox bearings, pump bearings, fan bearings, and machine tool way lube systems.
- Bearing Oil Benefits: These series prevent thermal degradation of bearing lube oil, maintain film thickness for reduced friction/wear, and extend bearing life without oversized main-system coolers.

Bearing Oil Cooling Systems
Bearing oil coolers target low-flow lubrication returns from bearings in spindles, motors, gearboxes, pumps, fans, and rotating equipment — removing heat to preserve oil film strength, reduce friction/wear, and prevent overheating failures.
BM Series: — Motor-mounted air-cooled coolers that attach directly to TEFC electric motors (NEMA 48–365 frames) — providing integrated, space-saving bearing oil cooling for machine tools, gearboxes, and motor-driven equipment.
BME Series: — Compact standalone coolers with small 1/40 HP 115V electric fans in single or two-pass designs — ideal for bearing lube circuits without direct motor mounting, such as remote bearings or retrofit applications.
Key Benefits
- Efficient cooling of low-flow bearing oil returns (typical <5–10 GPM)
- Maintains lubricant viscosity for proper bearing film thickness and reduced wear
- Prevents bearing overheating, scoring, spalling, and premature failure
- Compact footprint fits inside machine enclosures or on skids
- 300°F / 300 PSI ratings handle standard bearing lube conditions
- Economical, low-maintenance solution compared to full-system coolers
