This Estco Heavy-Duty Center-Bolt Safety Mounting Series is a versatile group of one-piece, low-deflection safety mountings designed for multidirectional isolation in heavy-duty applications. The mountings are rated by static load in the axial direction and dynamic loads up to three times the rated load can be handled. Although static loads in the radial direction are not recommended, dynamic radial loads are acceptable. The resilient element compressed during installation spreads at one end to form a self-contained rebound member. It features a bonded steel bushing that acts as a positive spacer. To install, lubricate the end of the mounting lightly with soapy water and, with an arbor press, push on the bushing to seat the mounting in the bore of the supporting member. Tightening the bolt until stopped by the integral spacer completes the installation.

LOAD DEFLECTION GRAPH

Deflections below the line X----X are considered safe practice for static loads; data above that line are useful for calculating deflections under dynamic loads
