Structure
*The disk set is comprised of a disk, bush and collar
Reference Number System
| NEH | 14 | W | – | N | H | 100 | J | D2 | X | A | H | 120 | J | D2 |
| Series | Size | (1) | (2) | (3) | (4) | (5) | (6) |
(1) Type: W = Spacer type, U = Unit spacer type
(2) Kind of hub: N = Standard hub, A = Adaptor hub, L = Long hub, U = Unit hub
(3) Shaft bore tolerance
(4) Bore diameter (Plain bore: R)
(5) Keyway tolerance: J = Keyway of New JIS normal type
(6) Set screw positioning
*Indicate the smaller bore diameter first
*Indicate the pilot bore (symbol “R”) first
*Unit Spacer Type (U-Type) cannot be combined with the adaptor hub (A-hub) type
Single-Side Adaptor Hub Type (A-Hub Type)/Unit Spacer Type (U-Type)
A-Hub Type
U-Type
The adaptor hub type provides a larger bore diameter than the standard hub. With the unit spacer type, the spacer unit can be mounted or removed without the need to disassemble the disk connecting section.
