| NORD-LOCK washers with enlarged outer diameter (sp) in combination with flanged nuts/ bolts are recommended for use on large/long holes, painted surfaces or soft materials, e.g. aluminium. |
|
NORD-LOCK is a pair of washers with a wedge-locking action meeting DIN 25201 which is a unique method using tension instead of friction. The rise of the cams between the NORD-LOCK washers is greater than the pitch of the bolt. In addition, there are radial teeth on the opposite side. The washers are installed in pairs, cam face to cam face.
When the bolt and/or nut is tightened the teeth grip and seat the mating surfaces. The NORD-LOCK washer is locked in place, allowing movement only across the face of the cams. Any attempt from the bolt/nut to rotate loose is blocked by the wedge effect of the cams.
NORD-LOCK washers positively lock the fastener in a joint which is subjected to any kind of vibration or dynamic loads.

An ONDUFIL ® spring washer is a round elastic item of the same family as our undulated, Belleville or Diaphragm spring washers, derived from a new manufacturing technology which consists of simultaneously rolling and corrugating a flat wire corresponding to the ring's width.
Due to smaller and smaller overall dimensions, compression forces (dips) in the field of larger and larger elastic deformations, and more and more varied stiffeners attainable with this complementary technology, an ONDUFIL® spring washer affords a perfect solution.
Our integrated design and engineering department using powerful computational software is capable today of responding rapidly to your needs.
Our totally integrated production workshop is capable today of making ONDUFIL® spring washers from a prototype for large manufacturing series production runs. |
|
| When suitably sized, the spring washer allows compensating for machining deviations, expansion plays, and ensures in any case that the ball bearing performs under the best conditions. |

· Single Turn Wave Springs
Single turn Wave Springs are perfect for tolerance take up and preloading an assembly. Smalley Single Turn Springs are coiled not stamped, providing for an affordable, precision load, stainless steel option. Wave Springs are stocked from ½” to 16” in both carbon and stainless steel.
· Bearing Preload
Single turn wave springs are ideal for bearing preload. The wave spring preloads the bearing through its outer race, taking up play in the bearing. By preloading a bearing, you will reduce bearing damage and wear.
Smalley’s Bearing Wave Spring Series comes in metric sizes to match popular bearing sizes. Over 150 standard bearing springs are available from stock, 16mm to 580mm. Specials are available for unique bearing sizes with No-Tooling-Charges™. |

Circular washer which are pre-formed with smooth flowing undulations, thus creating a product with spring properties when compressed.
Emmotts is internationally renowned for its range of waved washers used to pre-load bearings in electric motors. Recent development have enabled the company to address diverse applications in situations where relatively high loads are required from limited deflections, for example seals and valves. Split or slotted waved washers can be produced also and materials range from spring and stainless steel to copper and nickel alloys. |

Shaft nuts
Shaft nuts are highly precise mechanical components for mechanical engineering. They are used mainly for the attachment by camps on waves, can be used however also for the attachment of other elements, if particularly high requirements are placed against the attachment. Lock plates and grubscrews prevent the unintentional loosening of the connections.
Our shaft nuts are manufactured from high-quality steel and are subject to a high Fertigungsgenauigkeit. It is possible to achieve an even distribution of load on the threads and the camp unit what leads longer life span of the connection again to a higher rigidity and. Small leads of thread (fine threads) make an exact attitude of position and pre-loading for the shaft nut possible.
