Product Description
L Type HBN Jaw Spider Flexible Coupling – 20mm Bore, 1000 N·m, 1000 RPM, Cost-Effective
Factory direct | Black rubber spider | Low wear design | 1000 N·m torque | 1000 RPM | 20mm bore | OEM customizable | Construction industry grade
The Apexcoupling L Type HBN series is a cost-effective jaw spider flexible coupling designed for reliable power transmission in light to medium-duty applications. Featuring a simple three-component design – two sintered metal or aluminum alloy jaws and a black rubber (NBR) spider insert – this coupling delivers excellent vibration damping, misalignment compensation, and shock absorption at an economical price point. The black rubber spider provides low wear, oil resistance, and long service life, making it ideal for construction equipment, pumps, conveyors, compressors, and general industrial machinery.
✅ Cost-effective solution – simple design, easy maintenance, no lubrication required. OEM customization available.

Product Structure
Two Jaw Hubs – Sintered metal or aluminum alloy, precision-machined with curved jaws.
Black Rubber Spider (NBR) – The elastic insert that transmits torque, absorbs shock, and compensates for misalignment.
No Lubrication Required – Maintenance-free operation.
💡 The L Type coupling consists of only three components – two jaws and one spider insert – making it one of the simplest and most economical flexible coupling designs available. Power is transmitted between the jaw halves by the resilient spider insert.
Spider Material Options
| Spider Material | Properties | Best For |
|---|---|---|
| Black Rubber (NBR) – Standard | Oil-resistant, excellent flexibility and shock absorption, temperature range –40°C to +100°C | General purpose, cost-effective, low wear |
| Urethane | 50% greater torque capacity than NBR, good chemical resistance, temperature –35°C to 70°C | Higher torque applications |
| Hytrel | 3x torque capacity of NBR, superior temperature resistance –50°C to +120°C, excellent oil/chemical resistance | High torque, high temperature |
| Bronze | 3x torque capacity of NBR, extreme temperature –40°C to +230°C, excellent oil/chemical resistance | High torque, low speed (≤250 RPM) |
✅ The standard black rubber (NBR) spider offers excellent value for most applications, with good oil resistance and shock absorption.

FAQ
Q: What is an L Type jaw coupling?
A: An L Type jaw coupling (also called a spider coupling or jaw coupling) consists of two metal jaws and one elastomeric spider insert. Power is transmitted between the jaw halves by the resilient spider. It is a simple, economical design for light to medium-duty applications.
Q: What does “HBN” refer to?
A: HBN is a model designation within the L Type jaw coupling series, typically referring to specific size and configuration options.
Q: What is the standard bore size?
A: The standard bore is 20 mm. Custom bore sizes are available on request.
Q: What is the torque and speed rating?
A: Rated torque is 1000 N·m and maximum speed is 1000 RPM.
Q: What spider material is standard?
A: The standard spider is black rubber (NBR – Nitrile Butadiene Rubber) – oil-resistant, with excellent flexibility and shock absorption.
Q: What other spider materials are available?
A: We also offer urethane (50% higher torque capacity), Hytrel (3x torque capacity, higher temperature), and bronze (3x torque capacity, extreme temperature, low speed).
Q: Does the coupling require lubrication?
A: No. The L Type coupling is maintenance-free – no lubrication required.
Q: Can the coupling compensate for misalignment?
A: Yes. It accommodates angular misalignment up to 1° and parallel misalignment up to 0.4mm.
Q: What happens if the spider wears out?
A: The coupling features a fail-safe design – it can continue to transmit power even if the spider is damaged, minimizing downtime until replacement.
Q: Can I get a custom coupling?
A: Yes. We offer OEM customization – custom bore sizes, spider materials, and hub materials available.
