Product Information

This spiral guideway adopts an integrated precision forming structure with accurate positioning and stable rigidity, effectively reducing runout and clearance during operation.Traditional split guideways are complicated to assemble, difficult to ensure concentricity, and prone to shaking and wear after long-term use.

Recommendation: To avoid jamming or deviation caused by mismatched specifications, please provide the guideway model and matching installation dimensions when ordering this spiral guideway.

Product Features

Features of the RG Series Ball Screw Guide Rail

Core Structural Innovation

Replacing traditional steel balls with roller-type rolling elements, this design employs line contact between the rolling elements, guide rails, and sliders. Combined with a 45-degree contact angle, it overcomes the limitations of conventional point contact, achieving equal rigidity and load capacity in all four directions-up/down and left/right-for more balanced and stable force distribution.

Exceptional Performance

Under heavy loads, rollers exhibit minimal elastic deformation. Their ultra-high rigidity significantly enhances machining precision, meeting high-accuracy operational demands. Simultaneously, superior load-bearing capacity extends guide rail lifespan, reducing equipment maintenance and replacement costs.

Wide Range of Applications

Leveraging its high rigidity and heavy load advantages, it suits high-speed automated industrial machinery and various equipment with stringent requirements for rigidity and load capacity. Balancing precision and durability, it provides reliable support for efficient and stable equipment operation.

RG Series Installation Recommendations

Due to its roller structure and four-way high rigidity characteristics, installation precision directly impacts performance for the RG Series. The core process is as follows:

Pre-Installation Preparation

Installation Surface Preparation: Remove oil and burrs, grind to a roughness ≤ Ra3.2μm; inspect flatness (single rail ≤ 0.02mm/m, parallel height difference for multiple rails ≤ 0.01mm).
Product Verification: Inspect guide rail/slider appearance (smooth rollers, no scratches). Prepare accessories including bolts (minimum grade 8.8) and lithium-based grease.

Core Installation Steps

Guide Rail Fixing: Align reference edge with installation line. Pre-tighten end bolts (50% torque). After verifying straightness ≤0.01mm/m with dial indicator, tighten bolts from center to ends.
Slider Installation: Clean and apply grease, then smoothly insert into guide rail. For multiple sliders, use positioning rods to calibrate spacing and symmetrically tighten connecting bolts.
Preload Adjustment: Select rollers or adjust clearance based on light/medium/heavy preload requirements. Push slider to confirm uniform resistance without stuttering.

Post-Installation Adjustment & Protection

Lubrication & Dust Protection: Fill roller channels with grease (test seals for automatic lubrication); install dust caps; add bellows covers in dusty environments.
Testing:

No-load reciprocation: 10-20 cycles (no noise, uniform resistance)

80% rated load operation: 30 minutes, temperature ≤40°C, precision within tolerance.

Special Installation Considerations

Parallel Multiple Rails: Install reference rail first. Use laser interferometer to verify follower rail parallelism ≤0.005mm/m. Add intermediate supports for large spacing.
Vertical/Inclined Installation: Install lower limit block vertically. For inclines >30°, install anti-fall device. Relubricate every 10 hours.

Maintenance Guide

RG Series Linear Guide Maintenance Guide

Daily Maintenance

Replenish lithium-based grease every 100-500 operating hours (shorter intervals in dusty/humid environments), filling the roller channels completely. Daily: Wipe dust from guide rails. Weekly: Inspect dust seals for integrity and clean debris from bellows covers (in dusty conditions).

Condition Monitoring

Before startup, push the slide block to check resistance (no stuttering or abnormal noise). During operation, monitor vibration and noise. Monthly, measure guide rail straightness (≤0.01mm/m). Quarterly, retighten bolts (per manual torque).

Fault Handling

For stuttering, first remove dust and replenish grease; if ineffective, replace worn rollers and grind guide rail scratches (roughness ≤ Ra3.2μm). For precision loss, calibrate guide rails; if preload fails, replace rollers with original grade.

Long-Term Maintenance

Annually disassemble slides to clean raceways and replace dust seals. Replace guides when wear exceeds 0.02mm or hardness falls below HRC58. Store idle guides coated with rust-preventive oil in vacuum-sealed containers at 5-30°C with humidity ≤60%.

FAQ

Q: Our workshop environment is relatively harsh, temperature changes, and oil, roller guide can work normally?

A: Yes. This roller guide is made of special material, which can adapt to a wide range of temperature changes, and will not affect the performance due to thermal expansion and contraction. At the same time, the surface after anti-oil treatment, oil is not easy to adhere to, even in your workshop in such an environment, but also stable operation, to ensure the normal production of equipment.

Q: I am very interested in your roller guide, want to see the production process, can I visit your factory?

A: You are very welcome to visit our factory! We are always happy to let our customers know more about our production environment and process. You can contact our sales team in advance, inform your intention to visit and the expected time, they will help you to arrange the relevant matters.

Q: If I want a sample, do I need to pay for it?

A: For regular standard specification roller guide samples, within a certain quantity, we are free to provide. However, if you need special customised samples, due to the special production and customisation costs involved, you may be required to pay part or all of the sample production costs. However, if you formally place an order and the order quantity reaches a certain scale, we can offset this part of the sample cost according to the situation.

Q: If I buy a larger number of roller guides, packaging will have special treatment?

A: When you purchase a larger number, we will be based on the specific circumstances of the special packaging treatment. In addition to separate protective packaging for each guide rail, when they are centrally boxed, the space will be reasonably planned to avoid mutual extrusion. For the whole batch of goods, pallet packaging may be used, and the rails will be stacked neatly on the pallet and fixed and protected with winding film, which is convenient for loading, unloading and transporting, and at the same time, it can also better protect the rails.
