HRC Taper-Bush Jaw Flexible Coupling, for High-Power Pumps and Heavy-Duty Compressors

The HRC series jaw coupling is made of high-strength HT250 gray cast iron and innovatively combines it with a "taper-bush locking" structure. It is designed for demanding conditions such as pumps, compressors, and heavy machinery, with high power, high speed, and limited maintenance windows.

Item Specification
Model HRC series (F type / H type)
Body material HT250 gray cast iron
Surface treatment Black phosphating
Structure type Tapered bore (taper-bush type), jaw elastomer connection
Available sizes Full series including HRC110 / HRC130 / HRC150 / HRC180 / HRC200 / HRC225 / HRC270
Elastomer material Polyurethane (PU) spider, wear-resistant, oil-resistant, anti-aging, electrically insulating
Installation Taper-bush locking, convenient installation and removal, no need to move equipment
Compensation capability Compensates axial, radial, and angular misalignment

Key Product Advantages Key Selling Points Applications and Scenarios Contact Us

1. Quick taper-bush removal, zero-downtime maintenance: The tapered-bore (taper-bush) connection is installed and removed simply by tightening or loosening the bolts. Replacing the coupling or the elastomer requires no moving of the motor or equipment, greatly shortening maintenance downtime, an advantage that straight-bore couplings cannot match.
2. One-piece cast jaws, fail-safe design: Unlike ordinary spiders, the HRC drive jaws are cast as one piece. Even if the spider is destroyed under extreme overload, the metal jaws can still briefly interlock and transmit power, preventing the equipment from losing drive suddenly and protecting production safety.
3. Heavy-load capacity and high concentricity: HT250 cast iron is rigid and resists deformation under heavy load; the 8° taper bush grips the shaft and removes keyway clearance, giving high concentricity and minimal vibration at high speed.
4. Complete series, wide selection: Covers the full range from HRC110 to HRC270, and the polyurethane (PU) elastomer is wear-resistant, oil-resistant, and anti-aging, adapting to all kinds of harsh environments.

A maintenance revolution of "quick removal without moving the machine": Born to solve the pain points of difficult alignment and time-consuming installation and removal on large equipment such as big pumps and big fans.
A dedicated "airbag" for high-power equipment: High-strength cast iron + fail-safe structure is a reliable line of defense under heavy shock conditions.

Fluids and energy: High-power centrifugal pumps, compressors, gas turbines, and cooling tower fans.
Heavy industry and mining: Crushers, mining conveying equipment, and heavy-duty mixers.
Papermaking and metallurgy: Highly reliable connections for paper machine drive shafts and auxiliary metallurgical equipment.
