Custom Machined

Custom Machined Products

Bunting, in addition to its complete multi-casting capabilities, offers comprehensive custom machining facilities which produce bearings and components that are manufactured to the highest standards by our skilled craftsmen.

Bunting's computerized numerical controlled machining lathes, mills, and other ancillary equipment can produce components from inch to 20 inch in diameter. Bunting's design and engineering group are available to help our customers with their design of custom bearings and components free of charge.


Graphited Self-Lube Bearings

Bunting's graphited bearings provide a mechanical dry lubrication system. They are oil less and self lubricating.designed for long life without downtime.

Our standard alloys of C93200 bronze and aluminum bronze provide for extreme temperatures, from 400F to 800F. Graphited bearings are can be produced by Bunting in many other bronze alloys, to meet customers specific needs.

Lube-Align Standard Mounting

  • B 1 1/8 in
  • C 3/8 in
  • D 3/16 in
The unique, patented Lube-Align bearing products are made of self-lubricating, self-aligning SAE 841 bronze bearings permanently cast inside a 'fast mount' aluminum housing. Here's how Lube-Align bearings effect 4-way savings for OEM and maintenance engineers:

Self-Alignment
A special casting technique which locks the bearing inside the aluminum housing, yet allows sufficient freedom of movement to enable the bearing to position itself to line up with greatly varying shaft directions. This self-aligning feature saves by eliminating the costly hand labor normally required to align conventional bearings with shafts.

Self-Lubricating
The powdered metal bronze bearings used in Lube-Align products are actually 18% oil-impregnated. In action, the oil literally rises to the surface to create a smooth, hydraulic cushion for the shaft which prolongs both bearings and shaft life. Lube-Align bearings save by eliminating the need for additional lubrication for the prolonged life of the bearing.

Fast Installation
Lube-Align bearings are made in more than 115 standard sizes ranging from I.D. 18" to 2" for bearings and O.D. 34" to 3-12" for the aluminum housings. All of the bearings are equipped with exclusive ' fast mount' aluminum housings which save by keeping installation time and costs at an absolute minimum.

Low Unit Cost Savings
Devised and built on equipment which mass-produces Lube-Align bearings. Mass-production capacity combined with the increasing demand for Lube-Align bearings keeps unit costs in quantities at a consistently economical level.

(commonly used as a substitute to C93200 for non-lead applications)

Bunting continuous cast bronze bars of C89835 give superior quality and performance. Continuous casting achieves a high density grain structure, free of porosity, resulting in a reduction of tool wear and component rejects.
Solid and cored bars are stocked in 13" increments and 105" lengths, and are available in other lengths and non-standard sizes. Consider bars for use when you need special bearings, bearings for prototypes, or for emergency repairs.

Typical Properties: (Not to be used for specification purposes.)
Copper: 85.00 89.00%
Tin: 6.00 7.50%
Lead: 0.05% max.
Zinc: 2.00 4.00%
Nickel: 1.00% max.
Bismuth: 1.7 2.7%

Physical Properties: Continuous Cast
Tensile Strength, PSI:30, 000 min.
Yield Strength, PSI:14, 000 min.
Elongation:12% min.
Machinability Rating:70.
Minimum Operating Temperature:-450F.
Maximum Operating Temperature:500F.

C89835 is used as a no-lead replacement for C93200 material where lead-free material is required. Properties are similar to the C93200 material however; bismuth does not lubricate as well as lead so a constant supply of lubrication is recommended when using this material. Bunting
