JZP-4.0B Rubber Shock Absorber Anti-Rotation Slot Geometry Dry-Film Low-Friction Coating Isolator Mount

JZP-4.0B Rubber Shock Absorber

The JZP-4.0B is an assembled rubber shock absorber from the JZP-B series manufactured by Xi'an Hoan. The unit carries a nominal load of 4.0 kg and combines a steel spring core with a molded elastomer element. Installed between a vibrating source and its support, it absorbs shock and lowers transmitted vibration, keeping structure-borne noise away from floors, frames and housings. Typical mounting points include vehicle assemblies, general machinery, engines, compressors, fans and pumps.

Anti-rotation slot geometry and dry-film low-friction coating

Anti-rotation slot geometry. The housing of the JZP-4.0B is machined with slots that engage matching keys on the mounting face. When the isolator is bolted down, the slots hold the housing and the elastomer column in a fixed orientation around the mounting axis, so torque from the equipment or side loads during service cannot twist the isolator out of position. The load therefore stays on the designed axis and the rated stiffness of the unit is preserved.

Dry-film low-friction coating. The sliding faces of the JZP-4.0B carry a dry-film coating that keeps the contact friction low without liquid lubricants. The coating remains effective across the working temperature range of the isolator, does not collect dust or grit, and reduces stick-slip motion when the supported equipment expands, contracts or vibrates. This keeps the transmitted forces stable and simplifies maintenance.

Dimensional parameters

The JZP-4.0B follows the JZP-B layout. The row below gives the dimensional values of the JZP-B layout (D, H, h, A, B, d1, MG and R) used by the JZP-4.0B.

Applications

The JZP-4.0B fits mounting points where torque or side loads tend to rotate the isolator, such as engines and gearboxes in vehicles and vessels, generator sets, pumps, fans and compressors. The low-friction coated faces also suit equipment with thermal expansion, where the mount must allow small sliding movement without transferring additional force.
