Installation

For installation instructions, refer to Bushings, Installation Guide section. Heavy wall tubing is recommended for proper operation.

Rated static angular deflection

Rated static angular deflection is 15° for all parts. Maximum recommended deflection, static plus dynamic is 45° for all parts. Heavy wall tubing is recommended for proper operation.

Bushing Selection

To select a Square-Bonded Bushing for your requirements, compute the static torsional load it must support. Select from Tables 1-2, a bushing with static torque at 15° which is equal to or greater than the computed load.

Compute the static plus the dynamic torsional load. If this total load exceeds three times the static torque at 15°, select a larger size static torque rating part. Static radial load should also be computed and compared to the maximum static radial load listed above. Dynamic plus static radial load can also be three times loads listed above.

Custom Designs

Customized designs and special elastomer compounds for specific problems are available. These may result in spring rates and dimensions other than shown.
