REXNORD 4-BOLT

REXNORD 4-BOLT is a heavy-duty four-bolt flange mounted bearing unit engineered for radial load support in conveyors, fans, processing machinery and general industrial rotary equipment. It features solid cast iron housing with powder coating, integrated rolling elements and multi-lip sealing structure to resist dust, debris and minor moisture inside workshop environments. The flange bearing delivers stable radial load capacity for continuous rotating shafts, the flange bearing accommodates slight shaft misalignment during equipment operation. Maintenance technicians trust the flange bearing for long-running material handling and process equipment. The flange bearing adopts standardized four-hole layout for fast bolt fastening and simple field installation.

REXNORD 4-BOLT comes with built-in grease fitting for convenient re-lubrication, extending service life and reducing friction wear under cyclic load conditions. Its high-performance sealing assembly blocks contaminants from entering internal rolling components and prevents grease leakage during high-speed rotation. The load support absorbs heavy radial force and stabilizes shaft rotation in industrial drive systems. Reliable load support minimizes shaft vibration and cuts down noise during continuous operation. Operators can carry out periodic lubrication to maintain consistent load support performance for heavy duty cycles. Robust cast housing guarantees durable load support even under shock and intermittent overload conditions.

REXNORD 4-BOLT supports multiple bore sizes and seal variants to fit different shaft specifications, widely applied in mining equipment, food processing, HVAC fans and bulk conveying systems. Every unit undergoes load inspection, sealing test and dimensional calibration before shipment to ensure interchangeability. The rotary support design maintains precise shaft positioning for industrial transmission assemblies. This bearing unit provides dependable rotary support for non-stop production line operation. Easy disassembly and replaceable seals preserve stable rotary support performance over years of service. Industrial purchasers select this model for rugged, low-maintenance and cost-effective rotary support solutions.
