With us, you will always find the right product.
Every single industry requires products that are geared to very specific purposes. To support the requirements of a market holistically, we consistently analyse the current needs and future requirements of our customers.
This resulted in our W.TEC® product series with products for requirements-based solutions and industry-specific innovations. We guarantee optimal and consistent quality and first-class technical service. We can give you expert advice and best practices so that you will always find the right product, be it plastic cabs, slings, screws for thermoplastic materials or many more.
Due to their nature - radial ribs on the outer sides and wedge surfaces on the inner sides - wedge locking washers secure your connections reliably even under extreme loads.
- suitable for demanding screw connections
- secured by preload force instead of friction
- easy installation
- delivered already glued in pairs
Ring lock washers
The ring lock system combines the advantages of wedge lock washers with the special function of the ring, which permanently secures the two individual pulleys. Even with multiple use, it holds them together in the correct position.
- especially suitable for multiple use
- withstands dynamic loads, even when using lubricants
- fast installation also for non-specialist users
- no risk of incorrect installation due to the ring safety system
Combined wedge lock washers
The combined and at the same time efficient locking system for heavily loaded screw connections offers simple and quick mounting even in difficult installation situations.
- easy and captive installation due to internal slats
- can be combined with any commercially available screw
- reusable several times
- in steel and stainless steel with narrow and wide contact surface
The following four factors ensure the locking function of the washers: hardness difference, difference in the angle, friction difference and preload difference.
Since the surface of the wedge lock washer or ring lock washer is harder than that of commercially available screws, the radial ribs on the outer sides of the washer are shaped into the counter material (hardness difference). When tightening the screw connection, it creates a positive connection. Due to the specific pitch angle of the wedge surfaces on the disc, it comes to a self-locking if the screw should loosen automatically (angle difference).
The wedge sections at the joint faces of the two disc halves have a significantly lower coefficient of friction than the toothed outside of the discs. As a result, an unscrewing movement always leads to movement between the two disc halves and not between disc and counter-material (friction difference). If the wedge lock washer expands by a loose rotation, this leads to elongation of the screw and thus to an increase in pretensioning (preload difference).
