Steel-forming - Import export

Shrink disc to connect a hollow hub to a shaft. They are mounted on the OD of the hub and generate pressure on the hub wall by reducing the ID with wedgeformed rings, creating a press fit between the hub and shaft. They are suitable for static, dynamic and shock loads. for extremely high torques no axial shaft/hub offset when assembling selfcentring The version 23380014072 has high tensile ISO 4762 screws. Assembly Remove existing transportation locks. Clean and lightly oil shaft, internal and external hub diameters. Do not use MoS2 or grease. Slide shrink disc onto hub. Then slide unit (shrink disc/hub) onto shaft and position correctly. Gently tighten clamping screws one after the other by hand. Then use a torque wrench to tighten the clamping screws crosswise in several increments to the defined tightening torque MS. 1st increment approx. 33% MS 2nd increment approx. 66% MS

Coupling stainless steel 1.4057. Screws stainless steel 1.4301. For applications that require a small construction volume and low surface pressure. The keyless locking coupling can be fully recessed in a hub connection. for shaft diameters 6 20 mm suitable for hubs with low wall thickness minimum axial offset possible selfcentring Assembly Lightly oil keyless locking coupling on the tapered faces and contact points of the shaft and hub. Do not use MoS2 or grease. Insert keyless locking coupling in the hub seat and slide onto shaft. Tighten screws crosswise in several increments to the defined tightening torque. Dismantling Remove all screws and screw into the extraction threads of the front flange. Tighten screws crosswise in several steps until the keyless locking coupling loosens. Tolerances Shaft Recommended tolerance h8. Surface quality Rz ≤ 16 µm. Hub Recommended tolerance H8. Surface quality Rz ≤ 16 µm.

1.4401 stainless steel, similar to DIN 39. Grip suitable for DIN 950 handwheels.

Form C and F: Ball steel, ball seat high-carbon steel. Form G and J: Ball high-carbon steel, ball seat steel. Version: Form C and F: Ball hardened and black oxidised, ball seat phosphated. Form G and J: Ball phosphated, ball seat hardened and black oxidised. Note: The self-aligning pads serve as stops, rests and thrust pads in fixture construction. The seating face returns to the start position when the load is removed. Ball secured against rotation. Drawing reference: Form C: male thread, flattened ball, smooth Form F: male thread, flattened ball, diamond grip Form G: press fit, flattened ball, smooth Form J: press fit, flattened ball, diamond grip

Body tempered, black oxidised. Ball hardened, bright. Inserts: Form C, F hardened, black oxidised. Form M with carbide serrations, black oxidised. Form K white. Form E hardened, bright. Form O diamond impregnated surface comparable to 100 grade abrasive grit. Form P polyurethane surface, hardness 60 Shore. Note: Self-aligning pads are used to support and clamp unmachined and machined workpieces. In addition, they serve as stops, supports and thrust pads in fixtures and toolmaking. The ball can be removed from the housing by applying light pressure to the socket head screw. Ball secured against rotation. Advantages: Highly cost-effective as inserts can be exchanged. The built-in O-ring holds the ball in place and keeps dirt and foreign particles out, ensuring uniform movement. Drawing reference: Form C: flattened steel insert, smooth Form E: flattened stainless steel insert, smooth Form F: gripper face Form K: flattened POM insert, smooth

Material: Housing thick steel plate. Tyres steel-wire reinforced elastic solid rubber. Wheel body welded steel. Version: Housing press formed. Reinforced fork, base plate and centre pin. Double ball bearing with hardened shells in the castor head. Precision ball bearings in the wheels. Note: These castors are particularly impact and shock proof and assure a high service life. Wheel axle bolted.
