Ball Transfer Bearing Units — Smooth Multi-Directional Load Movement for Conveyors & Assembly Lines

When your conveyor line, assembly table, or material handling station demands frictionless, multi-directional movement without manual repositioning, a reliable ball transfer unit is the answer. Engineers, fabricators, and production line builders rely on CY-series ball transfer bearing units to keep workpieces gliding effortlessly across surfaces — eliminating bottlenecks and reducing operator fatigue.

Each CY-series unit consists of a large load-bearing top ball seated in a housing packed with smaller recirculating support balls, all enclosed in a robust shell. Available in three materials — Carbon Steel, Nylon, and Stainless Steel — and five load-capacity sizes: CY-8H (8 mm / 0.31 in top ball), CY-12H (12 mm / 0.47 in), CY-15H (15 mm / 0.59 in), CY-22H (22 mm / 0.87 in), and CY-30H (30 mm / 1.18 in). Housing outer diameter ranges from approximately 17 mm to 60 mm (0.67 in – 2.36 in) depending on model.

Typical use cases include gravity conveyor roller tables for box and tote handling, omnidirectional transfer decks in packaging and sorting lines, and DIY workbench inserts for rotating heavy jigs or fixtures without lifting. Long-tail applications such as "ball transfer unit for conveyor table", "omnidirectional roller bearing insert", and "CY-series ball caster for assembly line" are all served by this versatile product family.

🔧 Compatibility: Fits standard mounting holes for CY-series ball transfer units. Carbon Steel suits general dry environments; Nylon suits lightweight or noise-sensitive applications; Stainless Steel suits corrosive or washdown environments. Verify load rating and housing diameter against your table or frame specification before ordering.

✅ Key Features of These Ball Transfer Bearing Units

🔄360° Multi-Directional Rolling — The large top ball rotates freely in all directions, allowing workpieces to be pushed, rotated, or redirected without lifting, ideal for conveyor transfer points and sorting stations.
⚙️Three Material Options — Choose Carbon Steel for cost-effective general use, Nylon for lightweight and electrically non-conductive applications, or Stainless Steel for corrosion-resistant and washdown-safe environments.
📐Five Size Variants (CY-8H to CY-30H) — Top ball diameters from 8 mm (0.31 in) to 30 mm (1.18 in) cover a wide range of load capacities, from light-duty PCB handling to heavy-duty pallet and fixture transfer.
🏗️Compact Flanged Housing — The flanged or threaded housing design allows flush or recessed mounting into conveyor frames, workbench tops, and transfer plates with standard tooling.
🔇Low-Noise, Low-Friction Operation — Recirculating inner support balls distribute load evenly, reducing rolling resistance and operating noise compared to fixed casters or plain slides.
🔩Drop-In Replacement Compatibility — CY-series dimensional standards are widely adopted, making these units direct drop-in replacements for worn or damaged ball transfer inserts in existing conveyor and assembly fixtures.

❓ Frequently Asked Questions

How do I choose the right CY size for my application?

Select based on two factors: the load per unit and the mounting hole diameter in your frame or table. CY-8H and CY-12H suit lighter loads (typically under 20–50 kg per unit), CY-15H and CY-22H cover medium loads, and CY-30H handles heavier workpieces. Space units evenly so the total load is distributed across all installed units. If in doubt, size up.

What is the difference between Carbon Steel, Nylon, and Stainless Steel versions?

Carbon Steel units offer the highest load capacity at the lowest cost and suit dry, indoor environments. Nylon units are lightweight, electrically non-conductive, and gentler on delicate workpiece surfaces — ideal for electronics assembly or noise-sensitive lines. Stainless Steel units resist corrosion and are suitable for food processing, washdown, or humid environments where rust is a concern.

Are these ball transfer units strong enough for heavy industrial use?

The CY-30H Carbon Steel and Stainless Steel variants are designed for heavier-duty applications. For precise load ratings per unit, refer to the variant specifications or contact us to confirm suitability for your specific load and duty cycle. Using multiple units in a grid pattern significantly increases total table capacity.

Will these units rust or corrode in a wet or outdoor environment?

Carbon Steel units are not recommended for wet or outdoor use without additional protection, as they can rust over time. For corrosive, humid, or washdown environments, choose the Stainless Steel variant. Nylon units resist moisture but have lower load capacity and are best for indoor, light-duty wet conditions.

Are these compatible with standard conveyor table mounting holes?

Yes — CY-series ball transfer units follow widely adopted dimensional standards, making them compatible with most standard conveyor frames, transfer decks, and workbench inserts designed for CY-type units. Always verify the housing outer diameter and mounting style (flanged vs. threaded) against your existing fixture before ordering.

Can I use Nylon ball transfer units on a painted or finished surface without scratching?

Nylon balls are softer than steel and are less likely to scratch or mark finished surfaces. They are a popular choice for assembly lines handling painted panels, glass, or coated components. However, for very delicate surfaces, test with a single unit before full installation to confirm suitability.

How many ball transfer units do I need for my table or conveyor section?

A common rule of thumb is to space units on a grid of 100–200 mm (4–8 in) centers, depending on the size and rigidity of the workpieces being moved. Divide the maximum expected load by the per-unit load rating and add a safety margin of at least 20–30%. For irregular or heavy loads, consult a mechanical engineer for a formal layout calculation.
