Часто задаваемые вопросы о роликах для раздвижных дверей
What are the main types of sliding door rollers?
The main types are single-wheel rollers, tandem (double-wheel) rollers, embedded rollers hidden in the profile, multi-wheel roller strips, bracket or hanging rollers, and top-hung rollers that carry the door from an overhead track. The door system and the panel weight decide which type fits.
Which is better for sliding door rollers, nylon or steel wheels?
Nylon wheels are quieter and gentler on aluminum tracks, so they suit windows and most residential doors. Steel and stainless steel wheels carry heavier loads and suit large doors on steel or stainless tracks. POM and PU wheels sit in between, with smoother and quieter running than standard nylon.
How much weight can a sliding door roller hold?
It depends on the roller type. As a planning guide, window rollers carry about 20–40 kg per sash, single-wheel door rollers 40–80 kg per panel, tandem rollers 80–150 kg and multi-wheel roller strips 120–300 kg. Choose rollers rated for at least 1.5 times the share of weight each one carries.
How do I measure a sliding door roller for replacement?
Measure the housing length, width and height, the wheel diameter and width, the groove profile, the adjustment range and the fixing method, and note the track shape. Sending the old roller or a profile section is the fastest way to get an exact match.
What is the difference between ZZ and RS bearings in rollers?
ZZ bearings have two metal shields and run with lower friction, which suits indoor doors and windows. RS bearings have rubber seals that keep out fine dust and water, which suits patio doors, bathrooms and coastal sites.
Why does my sliding door jump off the track?
The usual causes are a wheel groove that does not match the track, worn wheels, or rollers set at different heights. Match the groove profile to the track, replace worn rollers and adjust both rollers so the door sits level.
Can you make rollers to match our profile or sample?
Yes. Send a sample roller, a profile section or a drawing. We match the housing to the cavity and choose the wheel material, color, groove and bearing, using our 2000+ existing molds or a new private mold.
What is the MOQ and lead time for OEM rollers?
MOQ starts from 1000 pcs and depends on the model. Samples from existing molds take 5–7 days and mass production 20–25 working days. Logo stamping and private-label packaging are available even for small quantities.
Is HIPAD a roller manufacturer or a trading company?
HIPAD is a manufacturer that started in 2000 with bearing assembly and produces rollers with its own injection molding machines, molds and assembly lines. HIPAD is ISO 9001 certified. Qingdao Hipad International Trade Co., Ltd. handles export.
