Ball screws - Import export

Ball end locating pins are specially designed to ease the locating process. The tendency to jam, caused by the locating hole not being at right angles to the pin or by the pushing force not being parallel to the pin axis, is minimized by the ball-end form (see illustration).

Ball element case-hardened steel. Thrust pad ETG 100 steel.

Ball-end thrust screws with full ball are used when a clean, polished contact surface is required.

Steel and stainless steel precision balls applications are limitless (bearings, control balls, screw balls, runner balls…).

The axis height of the spindle bearings matches the fixed bearing unit 2407801. The floating bearing units consist of a housing with deep groove ball bearing, which adapts axially to the linear expansion of the spindle.

Ideal elements for fastening cladding panels, Plexiglas covers etc. The oversized flange and the thread undercut ensure a stress-free, uniform force distribution on the respective surfaces. Projecting edges are kept to a minimum by the head height being kept as low as possible. An open-end spanner is used to screw the fastener in. The surface of the ball head screw is polished and, with regard to design optimised for the use in hygienic environments. The surface is polished to a surface finish of less than Ra 0.8 µm. Dirt and residue from products or cleaners seldom adheres and easy cleaning is ensured.

Surfaces which are not flat and parallel can be firmly clamped or supported with with a flattened ball, the movable ball can adapt itself up to 9°. Longer versions have been designed especially to be glued in. This allows mechanical connecting elements with external thread to be made cost-effectively for small and medium-sized series. The ball has a rotation lock.

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

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.

Body black oxidised. Thrust pin tempered and black oxidised. Drawing reference: M = ball pressure screw N = through hole for socket head screw DIN 912 1) rotation lock 2) screw rest 3) hexagonal nut

Tightening the ball-end thrust screw moves the jaw plates forwards. The workpiece is pushed against the fixed stop and simultaneously forced down onto the seating face. The seating face for the workpiece can be mounted directly on the machine table.

Sprocket steel. Ball bearing chrome steel. Screw and nut steel. Version Sprocket teeth hardened to HRC 50, electro zincplated. Ball bearing with sealing discs 2ZC3. Screw ISO 4017, grade 8.8, electro zincplated. Nut ISO 4035, grade 8, electro zincplated. Note For tensioning roller chains. The sprocket set can be combined with all tensioning elements to form a readytoinstall chain clamp. The ball bearings are sealed both sides, permanently lubricated and maintenancefree. The sprocket can be moved on the screw and thus adapted to the chain track. With the duplex and triplex version, precision spacer sleeves ensure correct chain guidance. Rigid mounting without a tensioning element is also possible. Can also be used as an idler sprocket.

Maintenance-free high quality link bushings. Sustainable constant use of force during opening and closing. Optimum stability through the conical, U-profile clamping arm.

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.

Housing hardened and black oxidised. Contact faces ground. Note: Locating bushes are placed in a fixture or interchangeable subplate and form the counterpart to the locating cylinder. The locating bushes are centred in a reamed hole and then fastened with 4 screws. The balls of the locating cylinder engage in the groove in the locating bush, thereby forming a fast, secure and highly accurate changeover unit, and reducing setup and changeover times. Attention: Please observe installation notes of the locating bushes.
