Our DIN products at a glance

Parallel keys to DIN 6885 for machine connections

Keyways

Keyways in accordance with DIN 6885, company standards, or custom dimensions—at Crummenerl GmbH, you can obtain high-quality keyways in all standard materials, with or without heat treatment.

Woodruff keys in semicircular shape for standardised applications

Disc springs

High-quality workmanship is essential for a form-fit connection with high torque transmission—and this is precisely where we excel as experts in CNC milling technology. If you’re looking for DIN 6888 disc springs, you’ve come to the right place.

Flat wedges for friction-locked connections

Flat wedges

Flat keys conforming to DIN 6883 are available ex works in a wide variety of designs. Upon request, we can of course accommodate custom specifications—such as specific heat treatments or deviations from standard materials. DIN 6883 flat keys are primarily used for the secure connection of shafts and hubs in heavy discs, wheels, couplings, or large machinery.

Nose keys for shaft connections with guide

Nose wedges

Nose wedges conforming to DIN 6887 play a particularly important role in large-scale industrial plants and machinery such as excavators and agricultural machinery. They ensure a secure connection between the shaft and the hub and enable even force distribution across the entire circumference. This requires precision manufacturing—and that’s exactly where we at Crummenerl GmbH come in. With our professional CNC milling technology and a wide range of available materials, we implement customer requirements precisely, quickly, and cost-effectively.

Saddle keys with straight groove for form-fit connections

Hollow wedges

Hollow keys conforming to DIN 6881 provide uniform force distribution in heavy-duty industrial equipment—they create a connection between shafts and hubs and offer the advantage of even force distribution while minimizing wear. Because they bear on multiple side surfaces simultaneously, they can transmit higher torques. For optimal applicability, DIN 6881 splined keys must comply with current dimensions and standards—and this is precisely where Crummenerl GmbH’s modern CNC milling technology comes into play, as we place the utmost importance on accuracy and precision.

Tangent wedges for friction-locked connections

Tangent wedges

High-quality workmanship is essential for a form-fit connection with high torque transmission—and this is precisely where we excel as experts in CNC milling technology. If you’re looking for DIN 6888 disc springs, you’ve come to the right place.

Suspension springs as connecting elements in machines

Suspension springs

Suspension springs compliant with DIN 28134 are primarily used in process engineering systems, tanks, and piping systems. Standardization ensures reproducible, reliable, and predictable spring performance—and the selection of high-quality materials also guarantees a high degree of durability. Thanks to the precision manufacturing you benefit from at Crummenerl GmbH, international applicability across many industrial sectors is guaranteed. Additionally, we promptly and cost-effectively implement individual customer requests as needed.

FAQs about our DIN products

DIN products are standardized components manufactured in accordance with established technical standards. These standards define the exact dimensions, tolerances, materials, and properties—making them components that can be used and interchanged internationally.

Perhaps the greatest advantage of standard DIN products is the reliability they offer in the planning phase. Designers and buyers can rely on clearly defined dimensions and technical specifications. In addition, DIN products are readily available and cost-effective to plan for.

Our standard product range for CNC machining includes, among other items, keyways (DIN 6885), disc springs (DIN 6888), flat keys (DIN 6883), tapered keys (DIN 6887), hollow keys (DIN 6881), tangent keys (DIN 268 or DIN 271), and suspension springs (DIN 28134).

Yes, our DIN-compliant products can be manufactured and machined from a variety of materials. Depending on the requirements, they can be produced with or without heat treatment.

In general, DIN products comply with established standards. At Crummenerl GmbH, however, you benefit from maximum flexibility—in many cases, custom dimensions or specific material requirements can be easily accommodated. In such cases, however, these are no longer DIN products, but rather custom CNC-machined parts.
