UB-1-A mounted on cross arm with XA-1 adapter
Bethea’s UB-1-A UNIVERSAL ROLLER is the solution to your search for a
quality engineered sheave that is lightweight (9.4 lbs), 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-A 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-A 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-A socket eye can be attached to optionally available
fittings, i.e., our CB-55 Clevis Ball; YCB-65 Y-Clevis Ball; OEB-55 Oval Eye;
BH-5L Ball Hook or SHB-1 Ball Safety Hook. UB-1-A 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-A socket eye can be
attached to optionally available fittings, i.e., our CB-55 Clevis Ball; YCB-65
Y-Clevis Ball; OEB-55 Oval Eye; BH-5L Ball Hook or SHB-1 Ball Safety Hook.
Other optional mounting adapters are also available: IA-1 for
Clamp Top Type Post Inuslators; IA-2 for Tie Top Post Insulators and XA-1 for
Crossarms. These adapters must be ordered seperately. The UB1-A has a 90 degree
adapter mounting lugs on each side of the frame. THese allow positioning the
sheave horizontally, if desired, when used with the XA-1 crossarm adapter or the
IA-2 when attached to a horizontal tie post insulator.
The gate latch is designed for safe, smooth, single-motion
hot stick or hand operation. The latch gate can be locked in the open position,
leaving the lineman's hands free for conductor removal from the sheave groove.
When the latch is released, the gate closes and locks automatically-nothing to
twist, turn or push.
The sheave groove is profile machined for concentricity, thus
permitting more precise sagging of the conductor. In addition, the universal
roller is available with urethane sheave lining (UB-1-AUL) or neoprene lined
sheave (UB-1-ANL)
Conrad Type, ABEC precision ground, deep groove ball bearings
are used in the sheave hub. They are permanently lubricated with Bethea BSG150
wide temperature range (-60F to 600F) synthetic lubricant.
