Universal Roller UB-1-C

April 13, 2016|New Products

Bethea Tool UB-1-C-DI Bethea’s UB-1-C Universal Roller is the solution to your search for quality engineered sheave that is lightweight (8.1 pounds), versatile, durable and dependable. It can be intermixed with similar stringing blocks and mounting attachments manufactured by others, without affecting conductor sag and tension.

The quality of the UB-1-C roller is not surpassed by any roller of its type. Its aluminum parts are cast from high strength A356 alloy, heat-treated to the T6 condition, giving it the capability of withstanding rough treatment under adverse conditions while supporting heavy loads.

The UB-1-C may be attached directly to ANSI Class 52-3 & 5 ball and socket insulators using the socket eye supplied as an integral part of the unit. If desired, the UB-1-C socket eye can be attached to the optionally available fittings, i.e. our CB-55 Cleavis Ball; YCB-65 Y-Clevis Ball; OEB-55 Oval Eye Ball; BH-5L Ball Hook or SHB-1 Ball Safety Hook.

Other optional mounting adapters are also available: UA-1A for Clamp Top Type Post Insulators 1A-2A for Tie Top Post Insulators and CA-1 for Crossarms. These adaptors must be ordered separately. They are not sold as part of the UB-1-C unless specified by the purchaser. The UB-1-C has 90° adapter mounting lug to allow positioning the roller horizontally, if desired, when used with the CA-1 crossarm adapter or the 1A-2A when attached to a horizontal tie post insulator.

The transfer of conductor or rope from the UB-1-C Universal Roller is quickly and easily accomplished by the removal of a single ball-loc pin. This pin is designed for safe, smooth, single-motion hand operation. The ball lock pin is secured to the roller with a welded closed link chain. When released, teh fram opens wide for conductor clipping.

The sheave groove is profile machined for concentricity, thus premitting precise sagging of the conductor. In addition, the universal roller is available with urethane sheave lining (UB-1-C-UL) and ductile iron sheave (UB-1-C-DI).

Double shielded, deep groove ball bearings are used in sheave hub. They are permanently lubricated with -5°F to 250°F grease. However, grease with wider temperature range are also available at request. Please specify with order.
