EVN Bushings

EVN Bushings

Features

  • ・No shaft hole or keyway machining required
  • ・Shorten the time required for setting
  • ・Easy positioning

Lineup

Two series can be used according to EVN SP pulley and EVN BTV pulley.

Abundant variations

Series from φ9 to φ160 eliminates the need for shaft hole and keyway machining.

EVN BHB Bushing Hubs

Overview

It can be used as a bushing-type hub by simply connecting it to a rotating body (impeller, etc.) of an air conditioner, etc. with a spigot and a bolt.

  • Materials

  • ：FC200～FC250

EVN Pulleys

EVN SP Pulleys

Features

When used in conjunction with EVN bushings, machining of shaft holes and keyways becomes unnecessary, making delivery management easier.

Lineup

Can be used with general V-belts, narrow belts, and SP belts.

EVN BTV Pulleys

Features

When used in conjunction with EVN bushings, machining of shaft holes and keyways becomes unnecessary, making delivery management easier.

Lineup

Can be used with general V-belts.

Center distance correction

■ Correction of center distance (when accurate center distance is required)

Compared to conventional pulleys for general use, BTV pulleys have a smaller difference between the nominal diameter and outer diameter (2c), so the outer diameter dimension (D) is smaller than that of general-use V pulleys. In addition, the groove width is slightly wider than that of general-use V-pulleys.
When using general purpose V-belts (A, B, C), the center distance can be approximated by adding △C compared to when using conventional pulleys.

EVN VP Pulleys

Features

Inch diameter V pulleys.

Lineup

Can be used with general V-belts.

  • *Shaft hole and keyway machining is required.
