Technical information for couplings Specifications Shaft displacement Axial and angular displacement are generally not a problem and are also easy to check. Conversely, great attention should be paid to radial shaft displacement, i.e. the lateral parallel displacement of the axes of rotation. This error must not exceed the value prescribed in the table.

Metal bellows couplingswith radial clamping hub Material: Hub aluminium. Bellows stainless steel. Version: Bright. Sample order: nlm 23000-012, D1 = 6 D2 = 6 (The hubs are supplied pre-bored). Note: Radial clamping of the hub for short mounting times and easy installation even in difficult to reach spaces. Take note of the required clamping screw tightening torque. Assembly: The shaft to hub bore fit should be a transition fit. The play should be min. 0.01 mm and max. 0.04 mm. i.e: shaft 0 28 k6 bore 0 28 F6. Bores smaller than D min. are possible, however an optimal transfer of the nominal...

Material: Hub aluminium. Bellows stainless steel. Version: Bright. Sample order: nlm 23002-0004, D1 = 3 D2 = 3 (The hubs are supplied pre-bored). Note: Clamping the hub with a grub screw is a cost-effective alternative to the metal bellows couplings with radial clamping hub (23000). Short mounting times and an easy installation even in difficult to reach places. Take note of the required tightening torque for the grub screw. To ease removal, a flat milled on the shaft is recommended. Temperature range: -20 °C to +150 °C. Assembly: The shaft to hub bore fit should be a transition fit. The...

Beam couplingswith radial clamping hub, aluminium Material: Aluminium. Version: Bright. Sample order: nlm 23010-1016, D1 = 2.5 D2 = 2.5 (The hubs are supplied pre-bored). Note: Zero backlash, torsionally rigid, resiliently flexible and maintenance-free full metal coupling for transmitting angle synchronous rotary movement. The innovative slit structure makes possible a very good axial, radial and angular flexibility with low reset force. Ideal for servomotors. Temperature range: -50 °C to +150 °C. Assembly: Recommended shaft tolerances h7. On request: Hub bores D1 and D2 with separate...

On request: Hub bores D1 and D2 with separate tolerance class or range. Drawing reference: 1) elastomer spider Elastomer dog couplingswith conical hub and clamping ring (similar to DIN 69002) Material: Spider polyurethane hardness Shore 98A. Hub aluminium. Conical ring carbon steel. Sample order: nlm 23021-010, D1 = 6 D2 = 6 (The hubs are supplied pre-bored). Note: This coupling series is particularly suitable for use in high speed main spindle or drill spindle drives. Before the plug-in assembly, both clamping ring hubs must be fastened to the shafts with the correct tightening torque....
