SAE 841 sintered bronze flanged bushings are the primary choice for self-lubricating bearings in home appliances and automated machinery due to their maintenance-free, high-speed/low-load performance. The integral flange provides both radial support and axial thrust capacity in a single component—ideal for motor shafts, consumer electronics, and OEM equipment requiring quiet, lubrication-free operation.

Small Electric Motors

Electric motor shafts, cooling fan motors, blower assemblies, and exhaust fan motors. The flanged design simplifies motor assembly by providing both radial support and axial location in a single component. SAE 841's self-lubricating properties deliver quiet operation—critical for motors in noise-sensitive environments. With speeds up to 1,200 SFM, these bushings handle typical motor RPMs without external lubrication.

Home Appliances

Washing machine drum bushings, refrigerator fan motors, vacuum cleaner motors, kitchen mixer shafts, and blender drive assemblies. Consumer appliances demand maintenance-free operation over thousands of cycles. Oil-impregnated sintered bronze delivers consistent lubrication throughout the product lifecycle. The flange provides secure mounting in plastic housings while distributing loads across a larger bearing surface.

Office & Business Equipment

Printer paper-feed rollers, copier drum shafts, scanner carriages, and paper-handling mechanisms. Business machines require smooth, quiet operation with zero maintenance over years of service. SAE 841's self-dampening properties reduce vibration and operational noise—essential in office environments. Flanged configurations simplify assembly in automated manufacturing.

Material Handling & Packaging

Conveyor idler shafts, packaging machine rollers, label applicator guides, and printing press components. These applications involve continuous rotation at moderate speeds. The 50,000 PV rating handles the load-speed combinations typical of material handling equipment. Oil-impregnated bronze eliminates the contamination risk that external grease creates in food packaging environments.

Lawn & Garden Equipment

Riding mower front wheel bushings, lawn tractor spindles, deck pivot points, and steering column bushings. Outdoor equipment faces seasonal use patterns—long storage followed by heavy operation. Unlike grease-lubricated bearings that can dry out during storage, oil-impregnated sintered bronze maintains lubrication readiness season after season. The flange provides thrust support for wheel assemblies.

Automotive & Fitness Equipment

Window motor shafts, seat adjustment motors, wiper assemblies, treadmill drive bushings, and exercise machine cable guides. These applications share a need for smooth, quiet motion in consumer-facing products. SAE 841 handles the intermittent operation cycles typical of automotive accessories and fitness equipment. Temperature stability from -40°F to +220°F covers both automotive under-hood and garage gym environments.

Custom Pressed to Your Specifications

For production quantities requiring non-standard dimensions, we can create sintered bronze flanged bushings pressed to your exact specifications. The powder metallurgy process compacts oil-impregnated bronze powder into a custom die, then sinters at high temperature to bond the particles while preserving the porous, self-lubricating structure.

Process Overview

  • Custom tooling created from your specifications (including flange geometry)
  • Bronze powder compacted under high pressure
  • Sintering bonds particles without liquefying
  • Oil impregnation fills interconnected pores
  • Finished parts maintain consistent density and self-lubricating properties

Best Suited For

  • Production volumes where tooling cost can be amortized
  • Applications requiring specific flange diameter or thickness
  • Designs needing consistent part-to-part repeatability

Machined from Sintered Bronze Bar Stock

For lower quantities, prototypes, or one-off requirements, we machine custom flanged bushings from oil-impregnated sintered bronze bar stock. The bar stock is manufactured through the same powder metallurgy process and arrives pre-impregnated with lubricating oil, maintaining the self-lubricating properties in your finished part.

Advantages

  • No tooling investment required
  • Custom flange dimensions without dedicated tooling
  • Faster turnaround than custom pressing
  • Ideal for prototypes and short production runs
