Technical Specifications

The Nexen 835000 DB Caliper Brake conforms to a set of technical specifications that make it suitable for a broad spectrum of industrial tasks. Model designation is 835000, featuring a double‑acting (DB) caliper configuration. Operating air pressure ranges from 0.5 psi to 10 psi, with a recommended nominal pressure of 5 psi for standard applications. The piston stroke measures 0.5 inch, delivering a maximum braking torque of 150 Nm at full pressure, while the minimum torque is adjustable down to 30 Nm through pressure regulation. The brake’s overall dimensions are 4.5 inches in width, 3.2 inches in height, and 2.8 inches in depth, allowing it to fit within compact equipment enclosures. Its weight is approximately 2.3 kg, contributing to ease of handling during installation. Construction material consists of hardened carbon steel for the caliper body and stainless‑steel seals to resist corrosion and wear. The external finish is a powder‑coated epoxy that meets ISO 12944‑5 corrosion‑resistance standards. Electrical connections are not required, as the unit operates solely on compressed air, simplifying integration with existing pneumatic circuits. The brake includes a built‑in pressure relief valve set to 12 psi to protect against over‑pressure events. It complies with ISO 1219‑1 pneumatic symbols and is CE‑marked for conformity with European safety directives. Optional accessories include a mounting bracket kit for shaft diameters ranging from 1 inch to 3 inch, and a quick‑release lever with a hand‑operated reset mechanism. All components are designed for a service life of at least 20 years under normal operating conditions, provided that routine maintenance guidelines are followed.

Installation Guide

The installation of the Nexen 835000 DB Caliper Brake follows a straightforward three‑step procedure designed to minimize downtime. First, verify that the mounting surface is clean, flat, and free of debris; apply a thin layer of anti‑seize compound to the bolt holes to ensure easy removal later. Second, align the brake’s mounting holes with the shaft flange, using the provided alignment pins to guarantee correct positioning. Secure the unit with the recommended torque of 12 Nm on each mounting bolt, checking for even pressure distribution. Third, connect the air inlet to a regulated supply line, ensuring that the line includes a filter‑regulator‑lubricator (FRL) unit to protect the brake from contaminants and to maintain consistent pressure. Adjust the pressure regulator to the desired operating pressure, typically 5 psi for most applications, and test the brake by applying air pressure while observing the engagement and release response. Finally, perform a functional check by cycling the brake several times under load conditions to confirm proper operation before returning the equipment to production. Detailed wiring diagrams and torque tables are included in the accompanying installation manual for reference.
