Regal Split Tapered Bushing Q1 2 Heavy Duty

Description

Product Overview

Regal’s Q1 2 split‑tapered locking bushing is engineered for demanding industrial environments where precision, torque capacity, and repeatable positioning are essential. Constructed from high‑strength alloy steel, the bushing features a solid flange that maintains concentric bores, eliminating run‑out and ensuring smooth power transmission. The double‑split barrel design provides positive clamping, while an external key on most sizes adds extra torque‑carrying capability. Available in both inch and metric bore sizes ranging from 3/8″ to 10″, the Q1 2 series accommodates a broad spectrum of shafts and splines, making it a versatile choice for machinery builders and maintenance engineers.

Usage

The Q1 2 bushing excels in applications such as gearboxes, conveyor drives, robotic arms, and heavy‑duty pump assemblies. Its robust construction tolerates high cyclic loads, making it suitable for continuous operation in manufacturing plants, material handling systems, and agricultural equipment. Installation is straightforward: the external key aligns with the shaft keyway, the double‑split barrel clamps securely, and the solid flange seats against the housing bore for a tight, concentric fit.

Why Choose Us

Regal combines decades of engineering expertise with rigorous quality control to deliver components that meet or exceed industry standards. Each Q1 2 bushing undergoes heat treatment and precision machining to achieve tight dimensional tolerances and surface finishes that reduce wear. The design’s positive drive key and double‑split barrel reduce the risk of slippage under peak torque, while the solid flange ensures alignment over the product’s service life. Backed by a comprehensive warranty and supported by detailed technical documentation, Regal provides confidence for engineers who cannot compromise on reliability.

FAQ

What is the advantage of the external key?

The external key engages directly with the shaft keyway, providing a positive mechanical link that transmits torque more efficiently than friction‑only designs, reducing the chance of slippage under heavy loads.

Can the bushing be re‑installed after removal?

Yes. The double‑split barrel allows the bushing to be opened, inspected, and re‑closed without loss of clamping force, provided the external key and flange surfaces remain undamaged.

What tolerances are guaranteed?

Regal guarantees bore tolerance of ±0.001″ (±0.025 mm) and flange flatness within 0.0005″ (0.013 mm), ensuring tight fit and minimal run‑out in precision assemblies.

Is the bushing compatible with metric shafts?

Absolutely. The Q1 2 series is offered in both inch and metric dimensions, and spline options are available to match a wide range of shaft standards.

How should the bushing be lubricated?

Apply a high‑temperature, high‑load grease to the barrel and flange surfaces before installation. Re‑apply at regular maintenance intervals based on operating conditions.
