From top roller bearings to custom sleeves and shafts, CIXI HOTO supports textile machinery customers with application-focused bearing and component manufacturing.
Cotton spinning machinery relies on many rotating components working together throughout fibre preparation, drafting and yarn formation. Each bearing position has its own requirements, influenced by operating speed, loading, available space and exposure to fibres and dust.
At CIXI HOTO, we combine textile bearing supply with precision component manufacturing to support machinery manufacturers, spare parts suppliers and maintenance service providers.
A useful starting point for selecting a textile bearing is to identify the machine and the function of the component.
| Machinery or application | Bearing terminology | Function |
| Draw frames, roving frames and ring spinning frames | Top Roller Bearing | Supports top roller rotation within the drafting system |
| Drafting systems | Bottom Roller Bearing | Supports bottom roller rotation; construction depends on machine design |
| Ring spinning frames | Spindle Bearing | Supports the rotating spindle |
| Rotor spinning machines, also known as open-end spinning machines | Rotor Bearing / Rotor Bearing Unit | Forms part of the rotor support arrangement, depending on the machine design |
| Rotor spinning machines | Opening Roller Bearing | Supports the opening roller, which separates fibres before they enter the rotor |
| Auxiliary drives and supporting mechanisms | Deep Groove Ball Bearing / Needle Roller Bearing | Provides bearing support where required by the individual assembly |
These names describe different applications rather than interchangeable products. For replacement enquiries, the original part number, drawing and assembly details are essential.
Top roller bearings are an important product category for customers working with cotton spinning machinery spares.
In a drafting system, the top rollers work with the bottom rollers to control fibre movement. Bearing selection therefore needs to consider the complete roller assembly, including its mounting dimensions, loading arrangement and maintenance requirements.
For enquiries involving a shaft with bearing sections at both ends, dimensions alone may not be sufficient. The spacing between the working sections, shaft geometry, sealing arrangement and rotation of each section should also be checked.
Rotor spinning machinery includes separate bearing positions for the rotor and the opening roller.
The opening roller separates the incoming fibres, while the rotor performs the yarn-forming process. Because these components perform different functions, an opening roller bearing should not be treated as the same product as a rotor bearing unit.
When requesting a replacement, identifying the exact assembly helps avoid confusion over terms such as “open-end bearing” or “roller bearing.”
Textile machinery also requires accurately manufactured metal components around the bearing.
The HOTO product photographs show a selection of bearing assemblies and precision parts, including sleeves, rings, shafts and stepped cylindrical components.
Our manufacturing support includes:
· Bearing rings and sleeves
· Precision shafts and stepped shafts
· Spacers, bushes and related cylindrical parts
· Custom components manufactured to customer drawings
For these parts, quality control starts with the material and continues through machining and dimensional inspection. Depending on the drawing, inspection may include bore and outside diameters, roundness, concentricity, runout, surface finish and the positions of grooves or lubrication holes.
For components that undergo further heat treatment or grinding, machining allowances and the delivery condition should be agreed before production.
To help us identify the product and assess manufacturing feasibility, please provide:
· Machine manufacturer and model
· Original part number or bearing designation
· Technical drawing and key dimensions
· Photographs showing the component and its installation position
· Material, heat treatment and operating requirements, where available
· Required quantity and expected annual demand
This information allows us to discuss the actual application and define the product requirements more clearly.
CIXI HOTO supports textile machinery customers with bearings and precision metal components, bringing together finished products and drawing-based manufacturing.
Whether you need a replacement bearing assembly or a custom sleeve, ring or shaft, send us your drawing or part details for review.
