Key Characteristics of the Pin & Bush Couplings RLP

The RLP series are fail-safe shaft-shaft connection with pins and elastic rubber elements for high demands. It also known as "Khớp nối bulong đai ốc RLP". The elastomer elements are made of polyurethane (PU) and the hubs (coupling halves) are made of steel.

The Couplings offer a number of practical advantages:
- Puncture-proof, corrosion-protected (phosphate coating)
- Low-maintenance, require no lubrication and allow wear parts to be replaced quickly.
- Compensate for axial, radial and angular misalignment between shafts.

Pin & Bush Couplings of the RINGFEDER® RLP series are two main types:
- Standard version without spacer (Type BWB)
- Version with spacer (Type BSB) for larger shaft distances.

Application of Pin and Bush Couplings RLP

Because of its robust design and ability to handle high torques with misalignment compensation, the RLP coupling is suited for heavy-duty industrial drive systems, such as:
- Pump and blower drives (shaft-shaft connections in fluid handling)
- Gearboxes in heavy machinery
- Conveyors, escalator drives, fan systems
- Steel, cement and mining industry drives where shock loads, vibration and reliability matter
>>> In short: anywhere you need a safe, reliable coupling between shafts under demanding conditions.

Why Choose Pin & Bush Couplings RLP?

- They provide backlash-free torque transmission even under extreme conditions thanks to their elastic pin & bush construction.
- Good durability: the polyurethane bush elements dampen vibration and shock, reducing wear on connected equipment.
- Versatile sizing across bore, diameter and torque classes allows matching to many industrial drives.
- Adjustable torque by selecting number of pins gives flexibility in design/engineering.
- The spacer version allows for wider shaft spacing without changing hub alignment.
