Product Family Overview

Industrial Brakes

RINGSPANN industrial brakes include DH/DV series electromagnetic caliper brakes (spring-applied, electromagnetically released disc calipers) and pneumatic/hydraulic caliper brakes, designed for safety braking and holding duty on cranes, conveyors, winches and stage equipment. DH series is vertically mounted, DV series is parallel-mounted, covering frame sizes 012 through 080 with DC24V/180V/205V coil options. The DS/DX series are electro-hydraulic thruster brakes, while HW/HS series are hydraulic released calipers for heavy-duty applications. DT series offers high clamping force up to 5,000 Nm.

Freewheels & Overrunning Clutches

RINGSPANN freewheels include FB series flange-mounted overrunning clutches (sprag type, oil or grease lubrication, torque range 560-2,500 Nm), FBF series (flange-mounted, up to 5,000 Nm), FKh series (hydrodynamic sprag lift-off design for high-speed applications), FGR/FGRN series (roller type with lever arms), FR/FRX/FRZ/FRS series (flange-mounted sprag clutches), FH series (enclosed drum-type freewheels up to 30,000 lb-ft), FCBM series (enclosed freewheel with electromagnetic multi-disc brake), and FXRW/FXRU series (torque-limiting freewheels up to 107,000 Nm). Used for backstopping, overrunning and indexing on conveyors, elevators and pumps.

Shaft-Hub Connections

RINGSPANN shaft-hub connections feature the RLK series locking assemblies, including RLK 110 (standard type, low radial height), RLK 110 K (corrosion-resistant, 2,800 Nm, 19-60 mm bore), RLK 130 (high torque up to 70,000 Nm, 20-180 mm bore), RLK 131/132 (compact cone clamping), RLK 133 TC/136 TC (Premium high-precision concentric clamping), RLK 200 (easy-release compact type, 20-400 mm), RLK 250 (quick-install easy-release, 4202 part number series), RLK 300 (independent clamping connection, 45-200 mm), and RLK 402/402 TC (extreme bending moment, heavy-duty, 25-300 mm). Keyless friction connection with high concentricity and easy assembly.

Internal Freewheels

RINGSPANN internal freewheels include FXNEN (press-fit outer ring installation), FR (standard internal type), DE (economical type), CN (compact internal type), and FZ P2RSEN / FZ PEN series (internal freewheels with sealed bearings). Designed to be embedded inside customer hubs for space-saving integration in gearboxes, transmission units and compact drive systems.

Cage Freewheels

RINGSPANN cage freewheels include E series (highest torque capacity), SF series (sprag-type cage with three variants), SFB series (interchangeable with BWX cages), and SF P series (high T.I.R. runout sprag cage). Supplied as core components for integration into customer drive systems, providing overrunning, backstopping and indexing functions.
