Product Description
Sprocket 20B-1 z=16, with hub
The sprocket 20B-1 shown is a simplex sprocket with 16 teeth, made with a hub, for chain with a pitch of 1 1/4" / 31.75 mm. Manufactured in accordance with DIN 8187 / ISO 606 from C45E structural steel (EN 10083-1), without tooth hardening - as a Polish manufacturer, Ozdowski supplies an economical version that is fully dimensionally interchangeable with the hardened variant of the same pitch.

Frequently asked questions
How should a chain drive be lubricated to extend its service life?
The lubricant should get between the rollers and plates of the chain, not just onto its outer surface - it is best applied to the lower (slack) part of the chain, just before it runs onto the sprocket. In a dusty environment, a thick grease works better, while at high speeds a lower-viscosity oil that penetrates the joints more easily is preferable.
Do you offer sprockets made to custom dimensions, outside the catalogue?
Yes, in addition to catalogue items we also manufacture sprockets to individual drawings or customer requirements - please contact the sales department and provide the required parameters (pitch, number of teeth, hub dimensions, material).
How do you calculate the pitch circle diameter of a sprocket?
The pitch circle diameter (Dp) is, in simplified terms, the line along which the chain rollers roll. It is calculated using the formula: pitch divided by sine (180° / number of teeth).
Will a sprocket from another manufacturer work properly with the chain I already have?
If the sprocket is made to the same standard (DIN 8187/ISO 606) and has the same pitch and number of strands, it should work properly with a chain of another brand - that is the purpose of standardisation in this industry. However, differences between manufacturers may concern, for example, hub dimensions or material, so these parameters are worth checking separately.
Where is this product used?
This type of sprocket is used in drives of agricultural and industrial machinery, including screw and bucket conveyors, feed conveyors, packaging machines and internal transport systems.
When placing your order, please check the current stock level of this gear - the lead time depends on it and is clearly stated according to the quantity available in the given warehouse.
