Product Description:
This top-notch component 4B1270.00-K09 enters the series of 4B1 PanelWare Panels, developed by the leading supplier B & R Automation. Its temperature range of -30°C to +80°C suits harsh industrial settings which preserves belt integrity under variable climates. A tensile strength exceeding 1200 N provides high load‑carrying capability which sustains power transmission under peak torque. Compatibility with pulley diameters starting around 125 mm matches standard B‑section drives which simplifies replacement on existing systems.
Its RoHS compliance certifies restriction of hazardous substances to protect against environmental contaminants. A weight of around 0.13 kg per meter ensures low inertial mass, reducing an energy consumption in continuous operation. Designation as a V‑Belt supports wedge‑type engagement and maintains stable belt seating under dynamic loads. The B‑section classification denotes a 17 mm top width design which aligns with conventional drive standards. Furthermore, a length of 1270 mm corresponds to precise center‑distance configurations that can minimize installation trial‑and‑error. 4 ribs facilitate multi‑rib engagement to distribute load evenly across the belt surface. An industry standard B‑section width of 17 mm provides consistent belt‑to‑sheave contact which enhances grip and reduces slippage.
Material construction of rubber reinforced with fabric cords of 4B1270.00-K09 panel and affords high flexibility under bending loads. A typical permanent elongation not exceeding 3% under ISO9856 guarantees minimal initial stretch to preserve tension settings. A top‑width‑to‑height ratio of about 1.6 to 1 maintains optimal wedge geometry and maximizes frictional engagement. Section height of 11 mm conforms to classical B‑Belt dimensions, guaranteeing compatibility with ISO 4183 pulleys. The reinforcing cords made of polyester deliver strong tensile support during start‑up. Compliance with ISO 1813 and RMA standards confirm oil‑resistant properties which protect against degradation in lubricated environments.
Frequently Asked Questions about 4B1270.00-K09:
Q: How is pulley‑diameter compatibility defined for 4B1270.00-K09?
A: The 4B1270.00-K09 fits pulleys with diameters no less than 125 mm which aligns with standard B‑section sheaves to streamline retrofit procedures.
Q: What does RoHS compliance indicate for 4B1270.00-K09?
A: This RoHS compliance for this panel module confirms absence of lead, mercury, cadmium, and other regulated materials which safeguard environmental and worker safety.
Q: How does belt mass affect 4B1270.00-K09 performance?
A: A mass of roughly 0.13 kg per meter for the 4B1270.00-K09 belt reduces rotational inertia which lowers motor load and improves energy efficiency over extended cycles.
Q: Which belt type applies to the 4B1270.00-K09 model?
A: The designation V‑Belt identifies a classic wedge‑shape profile which ensures consistent seating in sheave grooves under dynamic conditions.
Q: Why is the B‑section classification critical for 4B1270.00-K09?
A: Redesignation as section B anchors belt dimensions at 17 mm top width and 11 mm height and it guarantees compatibility with ISO‑standard pulleys.
