Product catalog summary

Overview
Renold Gears specializes in gear and coupling technologies, focusing on interchangeability, custom solutions, and availability. Their products are designed to seamlessly replace existing gear units, often enhancing capacity with advanced technology and materials.

Interchangeability
Renold's gear units are dimensionally interchangeable with those from other manufacturers, allowing for easy replacement and potential capacity upgrades.

Custom Solutions
Renold offers custom-made products tailored to specific customer needs, ensuring no compromise on availability or cost. These solutions range from complete packages to individual precision gears.

Availability
Popular gearbox ranges are readily available from local distributors, supported by extensive stocks from the UK manufacturing plant.

Coupling Selection Guide
Proper alignment of couplings is crucial during installation. Types of misalignment include angular, parallel offset, end float, and torsional flexibility. Selecting the correct coupling type and size requires knowledge of power transmission, drive characteristics, speed, and shaft dimensions.

Load Classification
Applications are classified by load type: steady (S), medium impulsive (M), and highly impulsive (H). This classification aids in selecting the appropriate service factor for coupling selection.

Service Factors and Selection
Service factors are determined based on the type of prime mover, duration of service, and load characteristics. These factors are crucial for selecting the appropriate coupling size and ensuring system safety.

Key and Keyway Dimensions
Keyways comply with British Standards, with dimensions provided for both metric and imperial measurements. Proper keyway selection is essential for ensuring the mechanical integrity of the coupling.

Crownpin Couplings
Crownpin couplings are designed for high power capacity and durability, suitable for demanding conditions. They feature neoprene rubber buffers for flexibility and shock absorption, extending machine life and requiring minimal maintenance.

Specifications
Crownpin couplings are designed for flexibility in installation with misalignment capabilities. They are constructed with cast iron half bodies and neoprene buffers, suitable for temperatures ranging from -30º to +95ºC. The standard range includes shaft-to-shaft, shear pin, and brake drum configurations.

Applications
These couplings are suitable for a wide range of industrial applications, including conveyors, cranes, fans, leisure rides, lifts, pumps, screens, washers, and general industrial uses.

Ordering Code
The ordering code for Crownpin couplings includes the size, number of pins, and types of pin and buffer halves, with options for plain bore or taper bush configurations.

Technical Specifications
The document lists detailed specifications for various coupling models, including power, torque, speed, bore sizes, dimensions, and mass. It also provides maximum angular and offset misalignment values for different models.

Component Spares
Renold supplies spare and replacement parts for Crownpin components, recommending Pinflex for new applications. The document includes a list of component numbers for pilot and taper bored pin and buffer half bodies.

Additional Products
The document highlights other Renold products such as Hydro-Service™ Leaf Chain, Roll-Ring™, Smartlink™, and various chain types, emphasizing their high performance, wear life, and resistance to fatigue and corrosion.
