Security screws - Import export

Sleeve 1.4305. Ball 1.4034. Spring 1.4310. LONG-LOK thread lock, Nylon.

Steel grade 8.8, black. Stainless steel A 2-70, bright. Drawing reference: L2 = approx. 2x thread pitch

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

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.

Housing, stainless steel 1.4301. Bearing, stainless steel 1.4125. Seal, rubber NBR. Note Pillow block bearings consist of a sealed singlerow ball bearing with a spherical outer ring which is mounted in a housing. Because of the spherical outer surface of the bearing, shaft misalignment can be compensated for. The bearings are manufactured with a plus tolerance. This results in transition or press fits when using shafts with htolerances. The shaft is secured by grub screws on the inner ring. In normal applications, pillow block bearings are maintenancefree due to the lifetime lubrication. In difficult environmental conditions relubrication can be carried out over the grease nipple. All housing dimensions are nominal dimensions for which the usual casting tolerances must be taken into consideration.

For the simple and safe locking of doors and hatches. Installed from the front without mechanical processing using M6 cylinder-head or cheese-head screws. Secured to prevent removal when locked. The key-operated version is supplied with 2 keys. The key can be removed in both positions (open and closed). The locks are keyed alike, i.e. they can all be opened using the same key (euro key 5333). The double-lug version is supplied with a double lug key. Drawing reference: Actuation: a) single-key system b) square 8 mm c) double lug 5 mm

Steel 1.0718. Stainless steel 1.4305. Version Steel black oxidised. Stainless steel bright. Note Rigid couplings transmit high torques without rotational play. They are used where there are no shaft displacements or alignment errors. Wearfree and maintenancefree. Screws secured to avoid vibration induced loosening. The maximum torque transmission can only be achieved through optimal installation and correct shaft dimensions. Maximum speed 4000 rpm.
