Structure of Standard roller
Shaft: Accurate shaft will be made of special machining mechanism
Pipe: Rollers are made of accurate pipe with state-of roundness and straightness
to ensure well-balanced rotation.
Ball-Bearing: Optimum fit given between ball bearing, shaft and housing, based upon years
of experience. Ball bearing provided with C3 group of clearance,ZZ shield
deep-groove to ensure a nice fit and off-set any expected temperature rise
during operation by means of internal clearance.
Housing: Housing made of deep-drawn material, cast on accurate mould, and will be
automatically welded to pipe simultaneity at both sides. Rigid and mono-block
structure so produced ensures to make it free from any looseness between
pipe and housing or breakage, resultantly provide with satisfactory durability
for high-speed conveyer susceptible to expected big impact during operation.
Labyrinth Seal: The particular labyrinth seal structure excogitated in our company is of
non-contact type, and so durable and has less rotation-resistance and
long life-span as to be of optimum structure, particularly for a long-
distance and large capacity conveyer for bulk material.
It is approved from the testing of national authoritative organization and
NC Company that Seal employed is of dustproof and waterproof type,
whose performance proved to be satisfactory and has by a long way
exceeded the GB and JIS standard after our repeated research and
development.

| Advantages︰ | 1. Low radial runout
Idler are made of precision steek pipe to ensure well-balanced rotation.
2.Low Roation Resistance,Energy-Saving
The rotation resistance factor of our idlers stay less than 0.01 through it varies with the roller dia.and bearing bore. This shows the advantage of our products in the way of energy-saving.
3.Permanent Lubrication
NC idlers are of factory-greassed,sealed-for-lifetime,fitted with precision deep-groove ball bearing(with ZZshields) at both ends,no extra lubrication is required. |
