STANDARD END MACHINING DIMENSIONS

Specifying standard machined ends results in quick deliveries. The machined ends shown below represent designs that are compatible with common application requirements for either simple or fixed bearing support. Dimensional data for these four types of ends is provided in the charts. Included in the chart are the Lock-Nut and lock washer identification. These standard ends may be machined on any length of screw to meet your specific need.

END TYPES:

1K, 2K, 3K and 4K are designed with a shaft extension and keyway for square keys.
1L, 2L, 3L and 4L are designed with a shaft extension without a keyway.
1N, 2N, 3N and 4N are designed to be a non-driven support end.

All EZZE-MOUNT™ bearing supports require a Type 3 end. Where standard ends do not satisfy requirements, special ends may be machined to special specifications. Please submit a print for a prompt and competitive quotation.
