Norgren PB-4 Pivot Bracket 1-3/4 2 2-1/2 in Bore

Product Description

The NORGREN PB-4 is a pivot bracket designed for use with air cylinders in pneumatic actuator assemblies. This mounting accessory allows the cylinder to pivot during operation, accommodating misalignment and angular movement between the actuator and the load. It is built to fit cylinders with bore sizes of 1-3/4 inches, 2 inches, and 2-1/2 inches. Maintenance technicians and industrial mechanics install this bracket when configuring or replacing pivot-mount cylinder arrangements on machinery, automation equipment, and process control systems.

The PB-4 is intended for use with Norgren nonrepairable air cylinders across the supported bore sizes. It is suited for industrial applications where a clevis or pivot mounting style is required to allow the cylinder body to swing freely through its stroke. Typical install scenarios include machine guarding, clamping fixtures, and linear actuation systems where load alignment cannot be guaranteed throughout the full stroke.

Installation Notes

Installation should be performed by a qualified industrial mechanic or pneumatic systems technician. Before servicing any pneumatic component, depressurize the air supply line and lock out the system per applicable OSHA lockout/tagout procedures. Verify bore size compatibility before mounting, and confirm that all fasteners are secured to the torque specifications listed in the original equipment documentation. Do not exceed the cylinder or bracket rated load capacity during operation.
