Browning Q1 1 1/16 Split Taper Bushing 1-1/16 Bore

Product Description

The BROWNING Q1 1 1/16 is a split taper bushing designed to mount sheaves, sprockets, and pulleys onto shafts in industrial power transmission applications. It features a 1-1/16 inch bore and uses a double-split barrel design to deliver positive, concentric clamping without distorting the mounted component. An external key drives positive engagement between the shaft and the hub, increasing torque carrying capacity over keyless designs. Licensed HVAC mechanics, millwrights, and industrial maintenance technicians install this style of bushing in belt-drive and chain-drive assemblies across commercial and industrial equipment.

This bushing fits into Q1-series taper bore hubs and is suited for residential and light commercial drive systems where reliable shaft mounting is required. The solid flange design maintains a concentric bore throughout the clamping process, which is critical in high-speed or precision-drive applications. Available bore options in the Q1 series span from 3/8 inch through 10 inches, covering inch, metric, and spline bore configurations across a wide range of shaft sizes.

Key Features

• Double-split barrel provides positive, even clamping force around the shaft
• External key on most sizes delivers positive drive and greater torque carrying capability
• Solid flange maintains concentric bore alignment during and after installation
• 1-1/16 inch bore fits standard inch-series shaft diameters
• Available in inch, metric, and spline bore configurations with bore range from 3/8 inch to 10 inches

Compatibility

Designed as an OEM-style replacement or direct-fit component for Q1-series taper bore hubs used in industrial belt-drive and chain-drive power transmission assemblies.

Installation Notes

Installation and removal should be performed by a qualified millwright or maintenance technician familiar with taper bushing procedures. De-energize and lock out the drive system completely before beginning any shaft work. Use the bushing's jackscrew holes to break the taper fit evenly during removal - never strike the bushing or hub directly with a hammer. Follow applicable ANSI and OSHA lockout/tagout requirements when servicing live drive equipment.
