Fenner Drives offers a wide selection of standard keyless bushings to meet most shaft/component mounting needs. However, we realize that to be innovative in a global marketplace, today’s engineers often require custom solutions. With unrivaled engineering expertise in keyless bushing design and material selection coupled with world class manufacturing capabilities, Fenner Drives is well positioned to offer Made To Order (MTO) Keyless Bushings.
From the ordinary to the extraordinary, our engineering team is ready to work with you. Together, we will develop a unique keyless bushing to meet your most demanding shaft/component mounting challenges.
All standard keyless bushings, with the exception of Trantorque SS, are made from either carbon or low-alloy steels. Certain applications may require the use of other materials such as:
- Stainless steel
- EXP stainless steel (allows for higher torque transmission without the use of lubricants)
- Tool steel
Special platings or coatings may be appropriate to deal with specific environmental or performance needs.
- Electroless (chemical) nickel with PTFE
- Zinc Chromate/Zinc Phosphate
- Zinc and aluminum in inorganic binder (water-based, VOC compliant)
The use of lubricants on threads and in some special cases, tapers, can have dramatic impact on keyless bushings properties.
- Light machine oil
- Synthetic grease
- Food grade grease
Performance of many B-LOC Keyless Bushings is determined by the screw grade used. Additionally, particular applications may benefit from a custom screw configuration.
- 12.9 and 10.9 socket head cap screws
- 10.9 hex head cap screws
- Fewer screws
- Smaller screws
In addition to special materials, finished, lubricants and fasteners that can be used with existing designs, the B-LOC and Trantorque fundamental architecture can be radically modified for special applications.
- Hand knobs in place of nuts on Trantorque Keyless Bushings
- Keyless bushings integrated into customer components
- Common OD with differing ID series
- Non-standard IDs and ODs
- Long units
- Short units
