Grippers and inserts are ideal for use in clamping arms, gripping systems, clamping fixtures, clamping jaws and self-aligning pads. The use of grippers allows the transfer of very high torque values and above average grip, even with hard materials and surface irregularities. Form O: The abrasive diamond surface is bonded firmly to the base. It is ideally suited to supporting smooth or slippery applications with a minimum of clamping pressure. This allows the diamond particles to get a firm grip on a very small area with minimum damage to the surface. The diamond surface offers excellent wear resistance. Form P: The polyurethane surface is vulcanised firmly to the ball. It is abrasion-resistant and does not discolour. It offers optimum protection against damage to delicate surfaces. The pearl-like surface gives a firm grip and allows air to escape so as to prevent any suction effect between the contact surface and the self-aligning pads.

These rounded half-dog point thrust screws are used when a punctiform thrust or support point are required.

Form A: Ball element case-hardened and black oxidised. Form B: Bright. Form C: Ball element case-hardened and black oxidised. Form D: Ball element bright. Form G: Ball element case hardened and black oxidised, foot with anti-slip plate. Note: The anti-slip plate absorbs vibrations and prevents the swivel foot slipping The loading indicated in the table is a recommendation up to which permanent static load the swivel foot can be used.

Steel class 45 H, black. Stainless steel A 2-70, bright. Drawing reference: L2 = approx. 2x thread pitch

The required torque is set by a set screw and a graduated scale. The set value can be secured using the lateral clamping screw. When the set torque is reached the grip audibly and palpably releases. The loosening torque is higher than the tightening torque so that the torque handle can be released without any problems. The internal thread version has a hole in the set screw so that the torque handle can also be used on threaded rods. Set torque accuracy ± 5%. On request: Other thread lengths.

Self-tapping threaded inserts for making high-strength, wear-free, vibration resistant screw connections in materials with low shear strength such as aluminium and aluminium alloys, brass, bronze, cast iron, duro and thermoplastics. The threaded inserts are tapered at the bottom and have a cutting slot. By screwing in they cut their own threads inside a receiver hole. This guarantees a completely secure and firm anchoring in the host material. Internal thread D1 acc. to ISO 6H. The threaded inserts with cutting slot spring slightly inwards in the slot region in some materials. This results in a screw locking effect. If this is not desired, we recommend the threaded inserts with a cutting bore.

Reinforced threaded inserts allow threaded holes which have been damaged, torn out or jammed to be used again or to be repaired. This makes it possible to recover scrap and rejects of expensive products. Reinforced threaded inserts are suitable for use in various materials, including light metals and casting. Inserts with internal threads larger than M6 are supplied with four locking pins instead of two. Permissible deviations: The medium tolerance class applies to the threads listed, i.e. 6H for nut threads and 6g for bolt threads. Other dimensions ±0.25 mm. With reinforced threaded inserts we also offer a version with a stronger cross-section for use in applications with greater stress. Technical information see operating instructions for threaded inserts.

For high demand hoisting and carrying tasks in safety-relevant areas (machine construction, load handling equipment, lifting tackle). The CE mark is impressed into the ring bolt. F2 permissible load under max. 45° per ring bolt. On request: Certificate of conformity.

Compact and light design, full loading on all sides. 4x safety factor against breakage in all loading axis. Rotatable 360°. Link swivel range max. 180°. The ball bearing allows the ring to rotate even under load. Lifting or securing loads, swivel rings have many uses. For the loading capacity to be valid it must be ensured that the ring is in line with the load. The swivel face must lie flat on the support beam and the screw must always be screwed in fully.

Shackles and bolts may vary in colour. Paint may cause the thread to be stiff.
