SKF Taper Roller Bearing， 170 mm ID， 230 mm OD - 32934 This SKF bearing has tapered raceways and rollers specifically designed to handle radial and axial loads acting at the same time。Its raceways meet at a common point on the bearings axis to provide a true rolling action and very low levels of friction。This reduces operational noise and allows the bearing to better maintain a pre-load。The units crowned raceway profile ensures even load distribution along the contact surfaces to reduce stress peaks at the roller ends。This also lowers the units sensitivity to misalignment and shaft deflection. Optimised surface finish supports the formation of a hydrodynamic lubricant for lower frictional heat and flange wear Excellent consistency of roller profiles and sizes for optimal load distribution Reduced temperature peaks during running-in periods to lessen wear Separable， single-row bearing for easier mounting， dismounting and inspection Application Information Rolling mills Gearbox manufacturing Mining industry Hoisting and lifting equipmentSKF 単列テーパーローラーベアリングは、複合負荷に対応すると同時にラジアル荷重とアキシャル荷重を同時に作用するように設計されています。軌道の投影線がベアリング軸のコモンポイントに接触することで、本格的な転がり動作を実現し、動作中の摩擦モーメントが低くなります。先細ローラーベアリングの軸方向荷重伝達能力は、接点角 α の増加に伴って増加します。コンタクト角度のサイズ(通常は 10 ° → 30 ° )は、計算係数 e ( e の値が大きいほど、コンタクト角度が大きくなります)と関係があります。 Can you use this component in rigid bearing applications 低摩擦 運用の信頼性の向上 ベアリングの剛性強化 通常、1 列先細ローラーベアリングは、2 番目の先細ローラーベアリングに対して調整されます。プリロードを適用することで、硬質ベアリングの用途を実現できます。 温度ピークが減少した実行イン期間 分離可能及び交換可能 内輪、ローラー、保持器アセンブリ(コーン)は、外輪(カップ)とは別に取り付けることができます。さらに、分離可能なコンポーネント(図6 )は交換可能です。これにより、取り付け・取り外し・メンテナンスの検査ルーチンが容易になります。Yes， this bearing is suitable for rigid bearing applications。You can achieve this setup by adjusting this bearing against a second tapered roller bearing and applying a pre-load.

Description。The SparkFun MicroMod Environmental Function Board adds additional sensing options to the MicroMod Processor Boards. This Function Board includes three sensors to monitor air quality(SGP40)， humidity temperature(SHTC3)， and CO2 concentrations(STC31)in your indoor environment. To make it even easier to use， all communication is over the MicroMod's I2C bus!。The SGP40 measures the quality of the air in your room or house. The SGP40 uses a metal oxide(MOx)sensor with a temperature controlled micro hotplate and provides a humidity-compensated volatile organic compound(VOC)based indoor air quality signal. Both the sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift and device to device variation.。The SHTC3 is a highly accurate digital humidity and temperature sensor. The SHTC3 uses a capacitive humidity sensor with a relative humidity measurement range of 0 to 100% RH and bandgap temperature sensor with a temperature measurement range of -40℃ to 125℃. The SHTC3 builds on the success of their SHTC1 sensor with higher accuracy(±2% RH， ±0.2℃)than its predecessor， enabling greater flexibility.。The STC31 measures CO2 concentrations based on thermal conductivity and has two CO2 measurement ranges：0 to 25 vol%； and 0 to 100 vol%. The measurement repeatability is 0.2 vol%， with a stability of 0.025 vol% / ℃. The measurement accuracy depends on the measurement range：0.5 vol% + 3% measured value； 1 vol% + 3% measured value. Using measurements from the SHTC3， the STC31 is able to provide humidity-compensated measurements together with improved temperature compensation. The STC31 can compensate for atmospheric pressure too - which is handy if， like us， you're up in the mountains!。The outstanding performance of these three sensors is based on Sensirion's patented CMOSens(R)technology， which combines the sensor element， signal processing， and digital calibration on a small CMOS chip. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.。Utilizing our handy M.2 MicroMod connector， no soldering is required to connect it to your system. Simply match up the key on your processor and function board's beveled edge connector to their respective key on the M.2 connector， then secure them to the main board with screws. The MicroMod Environmental Function Board can then be read via the I2C port. The board is equipped with the AP2112 3.3V voltage regulator， I2C pull-up resistors， power LED， jumper to disable the LED， and jumpers for alternative STC31 addresses.。Note：A MicroMod Processor and Main Board are not included with this MicroMod Environmental Function Board. These boards will need to be purchased separately.。MicroMod is a modular interface ecosystem that connects a microcontroller "processor board" to various "carrier board" peripherals. Utilizing the M.2 standard， the MicroMod standard is designed to easily swap out processors and function boards on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!。Get Started with the MicroMod Environmental Function Board。Features。Input voltage range。2.5V to 6.0V。Typ.。5V。via Main Board's USB connector。Typ.。～3.7V to 4.2V。via Main Board's LiPo battery Connector。I/O voltage。3.3V。AP2112 3.3V voltage regulator(rated 600mA)。Power LED。I2C pull-up resistors。Sensirion SGP40 Air Quality Sensor。Uses I2C interface。Address：0x59(default)。Operating voltage range。1.7V to 3.6V(Typ.。3.3V。)。Operating temperature range。-20℃ to +55℃。Typical current consumption。2.6mA。during continuous operation(at 3.3V)。34μA。when idle(heater off)。Output signal。Digital raw value(SRAW)：0 - 65535 ticks。Digital processed value(VOC Index)：0 - 500 VOC index points。Switch-on behavior。Time until reliably detecting VOC events：<60s。Time until specifications are met：<1h。Recommended sampling interval。VOC Index：1s。SRAW：0.5s - 10s(Typ. 1s)。Sensirion SHTC3 Humidity and Temperature Sensor。Uses I2C interface。Address：0x70(default， non-configurable)。Operating voltage range。1.62V - 3.6V(Typ.。3.3V。)。Operating temperature range。-40℃ to +125 ℃。Relative Humidity。Measurement range：0% to 100%。Typical accuracy：±2 %RH。Resolution：0.01 %RH。Temperature。Measurement range：-40℃ to +125 ℃。Typical accuracy：±0.2 ℃。Resolution：0.01 ℃。Typical current consumption(varies based on mode)。4.9μA to 430μA(Normal Mode)。0.5μA to 270μA(Low Power Mode)。Allows the STC31 to compensate for humidity and temperature。Sensirion STC31 CO2 Sensor。Uses I2C interface。Addresses：0x29(default)。， 0x2A， 0x2B， 0x2C。Operating voltage range。2.7V to 5.5V(Typ.。3.3V。)。Operating temperature range。-20 ℃ to +85 ℃。Calibrated for CO2 in N2 and CO2 in air。Measurement ranges。0 to 25 vol% in N2。0 to 100 vol% in air。Accuracy。0.5 vol% + 3% measured value in N2。1 vol% + 3% measured value in air。Concentration and temperature resolution：16-bit。Repeatability：0.2 vol%。Temperature stability：0.025 vol% / ℃。Start-up time：14 ms。Thermal conductivity sensor provides calibrated gas concentration and temperature output。Jumpers。PWR LED。I2C pull-up resistors。STC31 address selection。Note：The I2C addresses that are reserved for each sensor is 0x59(SGP40)， 0x70(SHTC3)， 0x29(STC31). A multiplexer/Mux is required to communicate to multiple SHTC3 sensors on a single bus. The SHTC3 uses the same address as the Qwiic Mux(0x70). For advanced users that are using multiple SHTC3's with the Qwiic Mux， you will need to adjust the Qwiic Mux's default address.
