Wide Ranges of Encoders for Your Applications！

Hollow shaft encoders contain a bore extending all the way through the encoder and are used extensively in all types of industries having the added advantage their ability to easily mount directly onto motor shafts and other types of shaft, without the need for a shaft coupling which are required for shaft encoders.
Hollow shaft encoders by Rongde Opitcs, China & Worldwide specialists & suppliers of incremental hollow shaft encoders. Whether you need an emergency repair or replacement encoder Rongde Optics team of specialists are happy to assist.

Semi hollow shaft encoders by Rongde Optics, China & Worldwide suppliers in Incremental Semi hollow shaft encoders. Speak to one of our encoder specialists today.
Semi-hollow shaft encoders are similar to hollow shaft encoders mounting in the same way. However the encoder’s shaft bore only extends partially through the encoder. As they only have a bore at one end, their ingress susceptibility could be considered as reduced by a factor of 50% in some cases.

Solid shaft encoder suppliers. Ronge Optics provide replacement solid shaft encoders, specialists solid shaft encoders as well as brand name encoders. Whatever your encoder requirements our team of encoders specialists can help & advise.
Solid shaft encoders are a more conventional encoder requiring a flexible shaft coupling to link the encoder shaft to the actual shaft that drives the encoder. Because a solid shaft encoder only has a small shaft, rather than a bore, the moving parts including the bearings and seals have a much reduced surface area. Therefore this type of encoder is generally more capable of running at higher speeds, with greater shaft misalignment because the effort is transmitted though the medium of the flexible coupling, which absorbs the axial and radial displacement, rather than transmitting the effects directly through to the encoder itself.
