FAQ
Q1: What materials can I customize for spherical plain bearings?
- Outer ring: Alloy steel, carbon steel, stainless steel, 52100 bearing steel
- Sliding surface: Steel-on-steel, reinforced nylon, PTFE, bronze
- Inner ring: 52100 bearing steel (most common), carbon steel, stainless steel
Q2: Do your bearings come with PTFE liners, or are they metal-to-metal?
We offer both options. For suspension use, we strongly recommend PTFE-lined bearings for self-lubrication and vibration damping. Metal-to-metal versions are available for industrial applications requiring grease lubrication.
Q3: Can these bearings be used for Uni-ball upper control arm upgrades?
Absolutely. Our COM-series bearings (such as COM10T and COM12T) are the most commonly used specifications in Uni-ball conversion kits and are strong enough for aggressive off-road jumps.
Q4: Can the bearings be welded directly during installation?
The bearing itself must NOT be welded. It should be pressed into a weldable bearing cup, then secured using snap rings or staking depending on your setup.
Q5: Do you offer staking services or tools?
Our bearings include V-grooves for easy staking. We can supply the appropriate bearing cups, but for staking tools, we recommend consulting your local machining or fabrication shop.
Q6: What if sand gets inside the bearing?
High-quality PTFE-lined bearings have tight tolerances that resist sand intrusion. For harsh desert conditions, we recommend using our high-misalignment sealed spacers to protect the bearing from contaminants.
Q7: Do you offer high misalignment spherical bearings?
Yes, we offer high misalignment spherical bearings. We have both standard models in stock and can also customize based on your requirements.
Q8: Can I request a sample for the spherical plain bearing before placing a bulk order?
Yes, you can request a sample before placing a bulk order. Samples of stock spherical plain bearings are free of charge, but you will need to cover the shipping cost. For customized bearings, a mold fee will apply.
Q9: What’s your average lead time for production?
Most standard models ship within 7–15 days. For custom orders, lead time will be confirmed after evaluating your specs and quantity.
Q10: Can you label my brand on the spherical bearings or packaging?
Yes, we support laser engraving on the bearings and custom packaging with logo labels or barcodes. Ideal for brand distributors.
Q11: What payment terms do you accept?
We accept T/T, PayPal (for samples), and L/C for large orders. For new customers, 30% deposit and 70% before shipment is standard.
