Sliding Shower Door Rollers are rollers installed at the top or bottom of a glass sliding door, supporting and guiding the door, ensuring smooth sliding along its track. Built-in bearings ensure smooth rotation, reducing friction and ensuring quiet and lightweight operation. Constructed of stainless steel, these rollers are designed to withstand the weight of the glass door and maintain balance, ensuring the shower door remains stable and stable even during frequent opening and closing.

Precision Construction

The Sliding Shower Door Rollers have a diameter of 39 mm and a thickness of 40 mm, equipped with an internal ball bearing system. The bearing outer ring is CNC-machined to a roundness tolerance of less than 0.02 mm, ensuring stable concentricity. The contact width between the pulley outer ring and the track is 8 mm, and the rollers can withstand glass door weights of 80 to 100 kg at rated load.

Material Strength

The main body is constructed of SUS304 or SUS316 stainless steel. SUS304 has a tensile strength of approximately 515 MPa, while SUS316 has a tensile strength of approximately 530 MPa, with a yield strength of 205 MPa. Both materials offer excellent bending and impact resistance, and can withstand the long-term dynamic loads of sliding doors.

Surface Finish

The surface is available in either matte or mirror polish. The matte surface has a roughness of approximately 0.8 microns (Ra), making it resistant to fingerprints and skid marks; the mirror polished surface has a roughness of approximately 0.2 microns (Ra), providing a high gloss and easy-to-clean finish. After pickling and passivation, a 3-nanometer-thick passivation film forms on the surface, effectively preventing air oxidation.

Bearing Performance

The bearing assembly utilizes a stainless steel inner ring and a high-density polymer spacer, filled with high-temperature-resistant grease, resulting in a coefficient of friction below 0.05. Bearing life testing has shown that the bearing can sustain over 500,000 cycles under standard load conditions while maintaining smooth rotation. This performance ensures smooth and stable operation with noise levels below 35 decibels and sliding resistance below 3 Newtons.

Installation Compatibility

The Sliding Shower Door Rollers are designed to accommodate tempered glass with thicknesses of 8 to 12 mm, and the mounting aperture accommodates standard M8 bolts. After installation, the clearance between the glass and the pulley is controlled to within 0.2 mm, ensuring high positioning accuracy. The components are compatible with a variety of upper and lower rail systems, ensuring high compatibility.

Home Shower Rooms

Sliding Shower Door Rollers are used in glass sliding door systems for residential shower rooms. The pulleys support the weight of the entire glass, ensuring smooth operation on the track. Their precision bearing structure ensures gentle opening and closing, reduces friction noise, and maintains a smooth feel over time, making them suitable for long-term installation in home bathrooms.

Hotel Bathrooms

Sliding Shower Door Rollers can be installed on hotel guest room shower partitions and can withstand an average of 200 to 300 opening and closing cycles daily without loosening. The polished outer ring of the pulleys offers approximately 30% better waterproof adhesion than ordinary stainless steel, maintaining a smooth, stable finish in humid environments, ensuring a stable user experience in high-end bathroom spaces.

Public Changing Areas

For glass partition doors in gyms, swimming pools, and other facilities, Sliding Shower Door Rollers maintain stability in high humidity and frequent opening and closing, ensuring the door slides smoothly without shifting or jamming. They meet safety and high durability requirements and facilitate centralized maintenance.

Office Partition Doors

Used in office sliding partition systems, the pulleys operate at less than 35 decibels, maintaining a quiet office environment. The door's sliding resistance is uniform, ensuring stable opening and closing travel and minimizing impact. This structure withstands frequent use over extended periods, enhancing space zoning flexibility and comfort.

Cleaning and Maintenance

Wipe the pulleys and rails with a soft cloth dampened with neutral detergent every two weeks to remove dust and scale. Avoid using acidic or alkaline solutions to prevent corrosion of the metal surface. After cleaning, dry the pulley thoroughly and keep it dry to prevent moisture from penetrating the bearing area.

Lubrication and Maintenance

Check the pulleys for smooth rotation every three months. If increased resistance is felt, apply a small amount of special lubricant to the bearings. Lubrication reduces friction, reduces noise, and extends bearing life. Avoid over-lubricating to prevent dust from attracting and affecting operation.

Tightening Inspection

Check the tightening of the mounting bolts and pulley bracket every six months. If loose, re-tighten with a wrench to the original torque to ensure a secure connection between the pulley and the glass. Also check to ensure the rails and door body remain parallel to prevent misalignment.

Rust and Moisture Prevention

When used in humid environments, apply an even layer of stainless steel protective oil to the outer surface of the pulley every quarter. This oil film reduces moisture adhesion and prevents surface oxidation. If not used for an extended period, cover the pulleys with a moisture-proof film for storage.

Track Cleaning

Check the tracks monthly for sand and foreign material buildup. Clean with a vacuum cleaner or fine-bristle brush if necessary. Keeping the tracks smooth prevents wear and vibration on the pulleys. After cleaning, apply a small amount of dry lubricant to maintain smooth gliding.
