SN:B101
Size:M2*21T*14L
SN B101 should be handled carefully because the visible title says 11T while the captured Size shows M2*21T*14L; this makes drawing confirmation part of the sales value.
The Super Screw is a high-performance PP gear (Polypropylene) or PVDF gear (Polyvinylidene Fluoride), both materials offering exceptional chemical resistance, impact resistance, and high-temperature performance, making them perfect for precise, low-noise power transmission. These gears are widely used in light-duty mechanical systems, especially in environments where quiet operation, durability, and long-term performance are essential.

11T 22 Spur gear belongs in the Gears and Screws category because it supports machine stability at a very specific point: 11T listing with source-size conflict that needs drawing confirmation. Before using it as a replacement, buyers should verify tooth count, bore, and body length against the installed part. The copy for 11T 22 Spur gear should keep that real equipment role visible.
PCB horizontal lines often run in humid, chemically active environments, so dimensional matching and material selection for 11T 22 Spur gear matter as much as the product name. A mismatch between title and size can lead to wrong quoting if the page does not tell buyers what to confirm. This gives the 11T 22 Spur gear page a stronger B2B purchasing angle.
Material Choice:
PP (Polypropylene): Offers excellent chemical resistance, low density, and is ideal for environments where chemical media are involved, with good impact resistance.
PVDF (Polyvinylidene Fluoride): Known for superior high-temperature resistance, it is widely used in environments that demand higher strength and temperature tolerance.
Wear Resistance:
Both PP and PVDF gears are self-lubricating, reducing friction and extending service life, thus minimizing maintenance requirements in high-frequency applications.
Low Noise:
Thanks to the material properties, the Super Screw gear operates at noise levels as low as ≤40dB, making it an ideal choice for applications requiring low-noise operation, such as office equipment and home appliances.
For 11T 22 Spur gear (M2*21T*14L), the trust point is precise replacement for 11T listing with source-size conflict that needs drawing confirmation, not a broad statement that QXY sells gears. QXY uses this page to show a careful engineering-sales process rather than pretending every old product record is perfectly standardized. The 11T 22 Spur gear page should ask for drawings or old-part photos so the sales team can verify module, tooth count, shaft interface, and installation clearance.
